Six toys (red and blue balls and blocks) are sorted one at a time by colour alone into a red hoop and a blue hoop, then each group is counted to show 4 red and 2 blue. The same toys are then sorted again by shape alone into 3 balls and 3 blocks, ending on the recap that we sort by one thing at a time.

Transcript

What the lesson says

Let's sort the toys into groups.

Look at just one thing: the colour.

Red toys go here, blue toys go there.

This ball is red, so it goes here.

This block is blue, so it goes there.

Now the rest. Red or blue?

Count the red toys: one, two, three, four.

Count the blue toys: one, two.

Check: all red here, all blue there.

Now sort the same toys by shape.

Balls go here. Blocks go there.

Count the balls: one, two, three.

Count the blocks: one, two, three.

Sort by one thing at a time.
