I am here today to bring you a number sense game that I use as a daily warm-up, but can also be used as a whole group, small group or math center/station activity.
Building number sense is something that all grade levels
One tool you can use to help build number sense is the 100 chart:
The activity I want to share is called "Arrow Arithmetic" in It Makes Sense! Using the Hundreds Chart to Build Number Sense (click below to view the book).
In this activity, students will receive a clue such as:
and will use the 100 chart to figure out the answer. So how do they figure out the missing number??? They have to use the arrows and some number sense!
Each arrow represents a direction you can go on the 100 chart: left (-1), right (+1), down (+10) and up (-10). Students can use a 100 chart to determine that the missing number is 45. Eventually, students will be able to determine the answer using mental math and even be able to solve problems that include diagonal arrows. And what does that eventually lead to?? Being able to add and subtract two-digit numbers using mental math!
Pretty cool, huh?!
I urge you to give this activity a try. My students LOVE it and beg to play it every day (which lately, we have been doing)! And they are REALLY good at it. :)
I made a little activity pack to go with the Arrow Game activity from the book:
I have also included a few practice pages:
It's even on sale for SuperBowl Sunday!
