Bar Model — 7 + 9 = 16 — free printable diagram

What is 7 + 9?

This part-whole bar model shows 7 and 9 as the two parts of one whole. Adding the parts gives the whole, so 7 + 9 = 16.

First part

7

Second part

9

Whole

16

Addition

7 + 9 = 16

Subtraction

16 − 7 = 9

• A part-whole bar model shows the whole on one bar and the parts that make it on the bar underneath. Here the two parts are 7 and 9, and together they fill the whole bar of 16.
• The parts can be added in either order — swapping them does not change the whole: 7 + 9 = 9 + 7 = 16.
• Covering up one part turns the same picture into a subtraction: 16 − 7 = 9 and 16 − 9 = 7.
• That is the fact family for these three numbers — the model is the reason 7, 9 and 16 belong together, whichever way round you write them.
