Representing Addition and Subtraction
Represent addition and subtraction using objects, drawings, and mental images
What a learner can do afterwards
- Use cubes or counters to show 3 + 2
- Draw a picture to represent a subtraction situation
- Use fingers to model an addition problem
The lesson
You already know how to add and take away. Now you will show it! Use blocks, drawings, or fingers to show a number problem.
Tap each block and count out loud.
Try it together
Mia draws 5 apples. She crosses out 2 she ate. Now 3 apples are left.
Good to know
You can use fingers too. Put up 3 fingers, then 2 more. Count all your fingers to find the total.
Show your addition and subtraction with objects, drawings, or fingers.
