Count objects in each category and compare category counts

Students will count the number of objects in each sorted category, record the count, and then compare category totals to determine which category has the most or fewest items. This connects sorting to counting and comparison.

12 rungs. A star at the top.

How many hexagons?

How it is taught

0:00 of 2:20

Count each sorted pile by itself.

Then compare the two counts.

Read it: Sort, then count

5 shapes are mixed up. Sort them: the circles on top, the rest below. Now count the circles: 3.

  1. Look at each shape.
  2. Put each one with its kind.
  3. Count each group.

Sorting puts the same kind together.

A sorted group is easy to count.

Then you can say which group has more.

Sort into kinds. Count each kind.

Counting every shape and saying 5 circles.

Sort first. Only the circles count: 3.

4 circles and 8 squares. How many more squares? — 4. Line them up: 4 squares have no circle partner, so there are 4 more squares.

3 cats vs 5 dogs

We sorted our pets into two groups: cats and dogs. Let's count to see which group has more!

Here are all the cats, sorted into one group on the left.

Let's count the cats together: one, two, three!

We have three cats. Let's write a three under the cats group.

Now look at the other group — the dogs on the right.

Let's count the dogs: one, two, three, four, five!

We have five dogs. Let's write a five under the dogs group.

Now compare the two numbers. Five is bigger than three. Five is more!
