Bar Model — 7 + 7 = 14 — free printable diagram

What is 7 + 7?

This part-whole bar model shows 7 and 7 as the two parts of one whole. Adding the parts gives the whole, so 7 + 7 = 14.

First part

7

Second part

7

Whole

14

Addition

7 + 7 = 14

Subtraction

14 − 7 = 7

• 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 7, and together they fill the whole bar of 14.
• Both parts are the same size, so this is a doubling fact: double 7 is 14.
• Reading it backwards gives the matching halving fact: 14 split into two equal parts is 7 each, so 14 ÷ 2 = 7.
• That is the fact family for these three numbers — the model is the reason 7, 7 and 14 belong together, whichever way round you write them.
