Task 1: Drop the Counters

For this task you will be creating addition and subtraction problems by dropping groups of objects.

Get a handful of small objects, things like counters and lego would work. Then drop some of them on the table.

Work out how many objects are on the table and how many are still in your hand. Show your working out using number sentences and by drawing a picture, like the example below.

Do this activity 4 more times, with a different total of objects each time.
