A farmer has 40 sheep. He wants to build pens for them, and each pen will hold 10 sheep. Figure out how many pens he needs for all the sheep by finishing the bar model.

The bar model shows the farmer’s 40 sheep. If each pen holds 10 sheep, how many pens will he need for all the sheep? We have to work out how many 10s there are in 40. We know that one 10 is 10, two 10s makes 20, three 10s makes 30, and four 10s makes 40. If a farmer has 40 sheep, and he wants to build pens for them, and each pen holds 10 sheep, the farmer will need to build four pens. Four times 10 is 40. There are four 10s in 40.
