Addition: Sum Sense
DRAG and drop the number cards to get the right answers in this online activity.
The challenge here is to work out what the sum problem is from the number cards you have to choose from. So if there are four cards number 9, 2, 1 and 1, the sum problem will be 9+2=11. It’s up to you to work out how the problem that fits together.
You are up against a timer – but you can change how many questions you have to answer in the time allowed, and how long that timer is, up to ten minutes.
An interesting challenge for second and third graders, this teaches kids to figure out how a sum works – and proves a useful way to keep brushing up on those skills, all the while getting faster and faster!
