20 problems

One step, in a setting you know.

  1. 1.

    A — 3

    There are 3 apples. Touching each one as you count keeps you from counting the same apple twice. Now you: put out 3 things of your own and count them.

  2. 2.

    B — Four dots

    Four dots sit in a little square, two on top and two below. That shape is worth remembering — after a while you will see four without counting. Now you: show 4 with your fingers.

  3. 3.

    C — 7

    There are 7 stars. Past five the counting words are the tricky part, not the touching. Now you: count to seven with your eyes closed.

  4. 4.

    D — A ten frame with six counters

    Six is a full top row of five and one more. Once you know the top row is always five, you can read the frame without counting every counter. Now you: what would 7 look like?

  5. 5.

    B — A triangle

    A triangle has 3 straight sides and 3 corners. The square has 4, and the circle has none at all. Now you: find something shaped like a triangle in your room.

  6. 6.

    B — 4

    A square has 4 corners and 4 sides — the same number of each. That is true of every shape with straight sides. Now you: how many corners does a triangle have?

  7. 7.

    A — Five fish

    Five is more than three and more than two, so the group of 5 fish has the most. Counting both groups first makes the comparison easy. Now you: which group has the fewest?

  8. 8.

    D — 3

    Two and one more is 3 flowers. The colors make them look like two groups, but the question asks about all of them. Now you: how many if one more red flower is added?

  9. 9.

    C — A circle

    A circle is curved all the way around and has no corners. The triangle and the square both have straight sides, and every straight side meets another one at a corner. Now you: what round things can you find near you?

  10. 10.

    A — 7

    After 6 comes 7. Counting on from a number, instead of starting again at one, is a habit worth building early. Now you: what comes right after 8?

  11. 11.

    B — 2

    There are 2 fish. Saying one number for each thing — and only one — is the whole skill here. Now you: hold up 2 fingers.

  12. 12.

    C — A ten frame with nine counters

    Nine counters leave exactly one empty box. Spotting the gap is faster than counting all nine. Now you: how many empty boxes would 6 counters leave?

  13. 13.

    B — A purple circle

    A circle is smooth all the way round with no corners. The square has 4 and the triangle has 3. Color does not decide the name — shape does. Now you: is a plate a circle?

  14. 14.

    A — 6

    There are 6 blocks. Counting on from five is quicker than starting at one each time. Now you: how many would there be if one more was added?

  15. 15.

    B — 3

    3 is smaller than 6, because you say 3 first when counting. Where a number sits in the counting order tells you its size. Now you: which is smaller, 2 or 5?

  16. 16.

    C — 4

    Two and two more is 4 stars. Two and two is a double, and doubles are worth learning by heart. Now you: what is double 3?

  17. 17.

    D — Two dots

    Two dots sit in opposite corners of the card. That is the two you see on a dice. Now you: which card shows one more than 2?

  18. 18.

    A — 3

    A triangle has 3 straight sides. The word "tri" means three, which is a useful thing to remember. Now you: how many sides does a square have?

  19. 19.

    B — 4

    After 3 comes 4. Counting on from a number, rather than starting again at one, is worth practicing every day. Now you: what comes right after 5?

  20. 20.

    C — One apple

    One is fewer than three and fewer than four. One is the smallest counting number you can have and still have something. Now you: which group has the most?
