In this interactive, beetles crawl into and out of a garden. Students work out how many beetles there are altogether while watching some beetles hide completely or partially beneath the leaves. Students choose a number for their answer and check it.
Counting Beetles Level 2 can be accessed http://fuse.education.vic.gov.au/?2JCUWA.
Display Counting beetles: Level 1 on an interactive whiteboard and show students how to count the beetles as they enter or leave the screen. Model counting with one-to-one correspondence and show how to check with a partner before entering answers. This interactive features scaffolding strategies for addition and subtraction.
As students show that they understand one-to-one correspondence, they can move to levels 2 and 3 of the activity.
