Bar Model — 6 + 6 = 12 — free printable diagram

What is 6 + 6?

This part-whole bar model shows 6 and 6 as the two parts of one whole. Adding the parts gives the whole, so 6 + 6 = 12.

First part

6

Second part

6

Whole

12

Addition

6 + 6 = 12

Subtraction

12 − 6 = 6

• 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 6 and 6, and together they fill the whole bar of 12.
• Both parts are the same size, so this is a doubling fact: double 6 is 12.
• Reading it backwards gives the matching halving fact: 12 split into two equal parts is 6 each, so 12 ÷ 2 = 6.
• That is the fact family for these three numbers — the model is the reason 6, 6 and 12 belong together, whichever way round you write them.
