On the Farm

Farmer Brown had 17 cows. 

He can fit 10 cows in each pen. 

• How many pens will he need to build for his 17 cows? Explain your thinking using a visual model.

• What if he has 36 cows? How many pens would he need then?

• And what if he had 54 cows? How many pens would he need?

• Is there a way to know the number of pens by just looking at the number of cows? If there is, explain your thinking to someone using a visual model.

** Challenge – what if he has 138 cows? How many pens would he need? Can you figure this out by just looking at the number? Explain how you found your solution.

Football

In a football game, the kicker kicked the ball 30 yards.  

In his next kick he kicked the ball 10 yards farther than his first attempt.  

How far did he kick the ball the second time?  Use a tape diagram (bar model) and a matching equation to show how you know.
