In the classroom

Teaching tips & learning objectives

Learning objectives

Mentally add 10 or 100 to a given number between 100 and 980
Mentally subtract 10 or 100 from a given number between 100 and 980
Record a completed equation (number, sign, number, answer) in a structured format

Teaching tips

Sort the two card sets into separate red and blue piles, as the directions specify, so students can clearly tell which pile supplies the starting number and which supplies the add/subtract amount
Have students set correct answers aside in a separate pile during play, then transfer only the confirmed-correct equations to the recording sheet afterward
Use this as a math-center or partner activity, since the fast, timed matching format works well outside whole-group instruction

Skills covered

Mental addition with three-digit starting numbers — students mentally add 10 or 100 to numbers from 100 to 980.
Mental subtraction with three-digit starting numbers — students mentally subtract 10 or 100 from numbers from 100 to 980.

Good to know

Questions teachers ask about this resource

How are the two card piles used together?

Each round, a student flips one card from each pile — one gives a number and a plus or minus sign (like 900-), the other gives 10 or 100 — and combines them into a single equation to solve mentally.

What happens to the cards during the timed round?

Students flip through the cards for one minute, setting correct answers into a separate pile as they go, then record the correct equations on the companion sheet after time is up.
