Who we are. Mission.io makes Missions: teacher-led, whole-class simulations where students use what they’re learning to work through a real scenario together.

Everything on this page works without us. The standards this page teaches are at the end, with a Mission where one exists, free. (There are two. In Finding Will, a space explorer is stuck behind debris, and his way out depends on a room of five-year-olds agreeing on how many.)

What kindergarten math looks like

Kindergarten math activities are problems where the class has to use the math to decide something, argue about whether the count is right, and leave each child answerable for a piece. This page teaches eight of the 22 kindergarten Common Core math standards, with an activity for six of them and a Mission for five.

The year has two big jobs. Whole numbers, at first with real objects: counting and cardinality (K.CC), the only grade with that domain, then adding and subtracting within 10 as putting together and taking apart (K.OA), and 11 to 19 as ten and some more. And shapes and space (K.G). Around them sits measurement and data: comparing lengths and weights, and sorting and counting by category (K.MD).

You know the activity that usually stands in for counting. A bag of buttons, a pair on the rug, one child counting while the other watches, and a number nobody checks. That’s counting with no reason. Math starts when the count has to be right because somebody is about to be promised ten and handed eight.

Six things that turn an exercise into math

Math isn’t short on time: grades K to 2 average about 55 minutes a day on it (2018 NSSME+). It’s short on talk. Observers in more than 2,500 first, third, and fifth grade classrooms found about 90% of instructional time was whole-group lecture or seatwork, and under 10% was small groups (Pianta and colleagues, 2007). That’s the gap worth closing, and at five it closes two children at a time.

  1. 1. A real problem with stakes the class can feel.

    “How many?” is an exercise. “The store can’t open until every bin has a true count” is a problem.

  2. 2. Apply, don't recall.

    A second round, with a bigger bin, that only works if the first round’s rules stuck: touch each one once, and the last number is how many. If the count can be finished without anyone checking it, it isn’t a math activity.

  3. 3. Group goals with individual accountability.

    The one most counting activities miss: one child counting, one child watching. When the group shared a goal and each student answered for a part, 84% of studies found a positive effect; without both, 17% (Slavin, 1991).

  4. 4. The teacher leads the thinking.

    Three questions, kneeling at the bin (how do you know you didn’t count one twice, how could I check it fast, what number goes on the label) beat a worksheet of twenty at the table.

  5. 5. A debrief where the class argues it out.

    The count is the setup. The talk afterward, about how one pair set out its bin so anyone could check it, is the practice the standards name: attend to precision (MP6).

  6. 6. A way to see who did what.

    If you can’t tell which child touched each cap once and which one guessed, you can’t teach counting. You can only collect the label.

How many caps? Ask the Checker.

The sheet at the end of the next section puts all six on the rug: role cards, bin labels, a five-frame card, and the tally. Get the sheet →

Counting collections, rebuilt (K.CC.B.5)

Pairs take a bag of bottle caps, buttons, or beans, count how many, set the count out so it can be checked, and record it. It’s a routine, not a one-off, which is why it’s here: kindergarten teachers run it weekly, and Math for Love and Illustrative Mathematics both build lessons on it. The way it usually runs is one child counting, one child watching, and a number nobody has a reason to get right. Here’s the version that hits all six.

Time
35 to 40 minutes, inside an average K to 2 math block of about 55.
Groups
Pairs. With 23 children, eleven pairs and one trio, where the third child is a second Checker.
Supplies
12 bags of 10 to 30 objects (bottle caps, buttons, beans, cubes), five-frame cards printed on the sheet, and sticky labels. About $0 if the room has junk.
Standards
K.CC.B.5 (count to answer “how many?” for up to 20 things, and count out a given number), with K.CC.B.4 (connect counting to cardinality) and the practice MP6 (attend to precision: count each one once, and say the last number as the total). Bigger bags stretch past 20 for children who are ready; the standard’s number is the floor, not the ceiling.

  1. Teach first, 8 minutesApply

    Dump 12 bottle caps in a pile and count them wrong on purpose: skip one, then count one twice. Ask the class to catch it. Then line them up and count again. Name the two rules: touch each one once, and the last number you say is how many. Then show one way to set them out, groups of five on a five-frame card.

  2. The problemStakes

    The class store is restocking, and the store manager (you) can’t sell anything until every bin has a true count on its label. A wrong label means a customer is promised ten and gets eight. Each pair gets one bin to count and label, and the manager will spot-check. Say the stakes out loud: without a true label, the store stays closed.

  3. Two roles, one job eachAccountability

    Written on the cards, with a name on each. Halfway through, the pair swaps, so each child counts and each child checks.

    • Counter

      The only hands on the objects, and moves each one as it's counted.

    • Checker

      Watches for a skip or a double, says "stop" when one happens, and writes the final number on the label.

  4. You lead the thinkingTeacher leads

    Three questions, kneeling at the bin: How do you know you didn’t count one twice? How could you set these out so I can check your count fast? What number will you write, and why that one? The hard part is keeping your own finger off the caps.

  5. Two rounds, so the rules have to stickApply

    Round one: count and label the first bin, 8 minutes, and the Checker reports to the manager. Round two: the pair swaps roles and takes a second, bigger bin, or the same bin set out in groups of five. The second round is where the organizing happens.

  6. The debrief, 8 minutesDebrief

    On the rug, with two labeled bins under the document camera. How did this pair set out its bin so the manager could check it? What did a Checker catch today? Who counted by fives, and why did that help? Kindergartners will name the kid who said “I put them in lines.”

  7. See who did whatSee who did what

    The observation sheet, four behaviors per child: touched each object once as it was counted, said the last number as the total, set the objects out on purpose, caught or fixed a miscount (their own or a partner’s). You confer at the bins, so a tally catches about half the room per session, and the labels catch the rest. It’s a weekly routine, so the sheet fills over a month.

(One bin will hold 29 things and a five-year-old who swears it’s a hundred. Hand her the five-frame card.)

Fill the twelve bags the week before, and count each one yourself. A label is only as true as the bag.

Five more kindergarten math activities, by standard

Five more on every kindergarten list: what each one is, how it usually runs, and what it needs to be a math activity, in the order the standards run.

Counting, adding, measuring, shapes

2. The 100th day collection (K.CC.A.1)

Needs 100 of something, brought from home.

On the 100th day of school, every child brings in 100 of something from home, like cereal pieces, pennies, or paper clips, and tells the class about it. The counting is real, and every child has done some. As usually run, though, the counting happened at the kitchen table, the bags go on a shelf, and you never hear which children can count to 100 by tens.

The fix

  1. Bring the collections to the rug, and have each child set theirs out in ten piles of ten.
  2. Count one collection together, ten at a time, with the whole class saying each ten aloud up to 100.
  3. Then have each child count their own piles by tens to a partner while you listen in.

No page for this one; the fix happens on the rug.

3. Ten-frame flash (K.CC.B.4)

Needs a set of ten-frame cards. Whole class.

You hold up a ten-frame card for a second or two, and the class calls out how many dots they saw. Done quickly, it builds the fast seeing of five and ten that counting rests on, and you’re leading the thinking the whole time. As usually run, though, there’s no problem to solve, the quickest voices answer every card, and you can’t tell who saw seven and who echoed a neighbor. Keep it as a warmup, and give the real counting to the bins above.

The fix

  1. Run it for two or three minutes at the start of math, right before the counting bins.
  2. After a few cards, ask one child how she knew so fast, like five on top and two more, so the class hears a way to see it.

No page for this one; a warmup doesn’t need one. Row 7 below is the Mission on this standard.

4. Shake and spill (K.OA.A.3)

Needs five two-color counters, a cup, a recording sheet.

A child shakes five two-color counters in a cup, spills them, and colors in how many landed red and how many yellow, again and again down a recording sheet. The counters do real work, since five turns out to be four and one, or two and three. As usually run, though, it’s a solo worksheet with nothing riding on the splits, and a page of colored circles doesn’t show who understood that every spill still makes five.

The fix

  1. Put children in pairs: the Spiller shakes and spills, the Recorder writes the split, and they swap after five spills.
  2. Hang a class chart with one question on it, how many ways can five land, and have each pair add the splits it found.
  3. Gather at the chart and ask which split nobody has spilled yet.

No page for this one; the fix above is the whole of it.

5. Measure with cubes (K.MD.A.2)

Needs connecting cubes, a book, a pencil. A station.

At a station, children snap cubes into a train beside a book and then a pencil, count the cubes, and say which one is longer. Kindergartners love the cubes, and the comparing is real. As usually run, though, there’s no reason to know which is longer, one child builds while the other plays with the extra cubes, and the station ends with no record of who compared what.

The fix

  1. Give the comparison a reason, like finding which pencils are too long for the class pencil box.
  2. Make it a pair job: one child builds the cube train, and the other checks for gaps and says the count.
  3. Have each pair circle the longer object on a picture card and write both cube counts, with both names on it.

6. The shape hunt (K.G.A.2)

Needs the room, and a tally card.

Children walk the room hunting for circles, squares, and triangles: the clock, the window, the sign on the bulletin board. The shapes really are everywhere, and children start naming them outside the worksheet. As usually run, though, the whole class hunts at once, the fastest pointer finds most of them, and nobody keeps track of who named what.

The fix

  1. Give each pair one shape to hunt, so the circle pair isn’t racing the square pair.
  2. One child is the Finder, who points and names each shape, and the other is the Tallier, who marks it on the card. Swap halfway.
  3. Collect the tally cards, which show you who found shapes and who counted them.

  • Our part · We make Missions

    Then the unit has somewhere to go

    Plenty of teachers rebuild these by hand every unit, and it works. A Mission is a teacher-led, whole-class simulation built to the bins’ own standards (K.CC.B.4 and K.CC.B.5): your class becomes the rescue party, the scenario is built from the counting you just taught, and the only way through is using it. After the bins, run Finding Will, and the unit has a day two.

    You're at the helm, not on the hook.

    Finding Will: counting, as a Mission

    Finding Will · Kindergarten · About 22 minutes · One device per student, plus your projector · Free with a teacher account

    Young students at a row of computer screens; one raises a hand while another laughs, and a green check shows on a screen.
    Young students at their screens, one hand up, a green check on the monitor.

    Will, a fellow space explorer, got himself trapped behind debris while he was out exploring. The class has to use its counting to get through a mysterious machine, compare groups to see which has more, less, or the same, and choose the best path to clear for Will. The story plays on the projector.

    There are no crews or stations in this one. Every child works on their own screen. The story goes the way most of the class chooses, and each child’s own choices and answers go into their report. You’re at the helm, asking how many are in this group, which one has more, and which path the class should clear.

    It’s built to the bins’ two standards (K.CC.B.4 and K.CC.B.5), with comparing groups alongside (K.CC.C.6), and the vocabulary is the unit’s: counting, more than, less than, equal to. It expects children who can count in order to 20 and have compared two groups before. Run the bins first, and tell the class why: Will only gets out if the class touches each one once and knows the last number is how many. The lesson prepares them. The Mission is what they’re preparing for.

    “This is the most fun they have all week, and they’re learning the whole time. I’m not going back.”

    What the report shows

    A Mission.io class report: the class score in each of six skills, from knowledge and application to collaboration, critical thinking, and resilience, with the class chart across the year below.
    A class report from a real Mission: the class score in each of six skills, then each skill across the year.

    Every Mission produces a report for every student, built from what that student did across the whole Mission, on the skills the Mission captured. The six it can capture are Knowledge, Application, Initiative, Collaboration, Critical Thinking, and Resilience. The first two are what a test already sees. The other four are the human skills every school promises. The test shows what they know. The report shows the rest. SEE THE EVIDENCE →

    Who's behind it

    Mission.io is a research and design organization with one job: make collaborative, active learning something a teacher can run every unit instead of once a semester, and put a report in your hands when it’s over. Over a million students have run a Mission. The research behind them is funded by the National Science Foundation and the U.S. Department of Education’s Institute of Education Sciences, and Mission.io meets ESSA Level II standards, as validated by Instructure.

Questions kindergarten math teachers ask

Which of these fits a math block?

Grades K to 2 average about 55 minutes of math a day, and both kindergarten Missions fit inside it: Dug’s Search and Rescue at 19 minutes and Finding Will at 22. The bins run 35 to 40 minutes. Ten-frame flash is a warmup.

Which kindergarten math standards does this page teach?

Eight of the 22 kindergarten Common Core math standards, across four domains: K.CC, K.OA, K.MD, and K.G. Two Missions cover five of them, K.CC.B.4 to K.CC.C.6 and K.G.A.1 with K.G.A.2. An activity on this page teaches six, among them the three no Mission covers: K.CC.A.1, K.OA.A.3, and K.MD.A.2.

Why pairs, and not groups of four?

At five, a pair is enough to need a Checker and small enough that nobody hides. Halfway through, the pair swaps, so every child counts and every child checks. With an odd number, make one trio with a second Checker.

How do I grade counting fairly?

Grade the count and the behaviors, not the neatest label. Is the label true, and can the Checker show how the pair knows? That’s one grade. The four-behavior tally, filled over a month of weekly bins, is the other. A child who counts slowly and touches every cap once is further along than one who guesses fast and gets lucky.

Is this aligned to my state's standards, not just Common Core?

Each Mission page lists its Common Core codes and the state sets it maps to. Both kindergarten Missions also map to Texas (TEKS), Florida (B.E.S.T.), and North Dakota’s math standards.

Twelve bins, and every label true

Day one, a problem by hand with the sheet. Day two, Finding Will after the bins, or Dug's Search and Rescue after the shape hunt, each with its 5-minute Teacher Preview. All free.
