Bar Model — 2 + 6 = 8 — free printable diagram

What is 2 + 6?

This part-whole bar model shows 2 and 6 as the two parts of one whole. Adding the parts gives the whole, so 2 + 6 = 8.

First part

2

Second part

6

Whole

8

Addition

2 + 6 = 8

Subtraction

8 − 2 = 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 2 and 6, and together they fill the whole bar of 8.
• The parts can be added in either order — swapping them does not change the whole: 2 + 6 = 6 + 2 = 8.
• Covering up one part turns the same picture into a subtraction: 8 − 2 = 6 and 8 − 6 = 2.
• That is the fact family for these three numbers — the model is the reason 2, 6 and 8 belong together, whichever way round you write them.
