Step 2<br />

Plan<br />

Step 3<br />

Solve<br />

Make a plan.<br />

Choose a strategy.<br />

You may draw a picture. Draw the road, rows, <strong>and</strong><br />

pumpkins.<br />

You can also make a model.<br />

Carry out your plan.<br />

Plan 1 Draw a picture. Draw the 10 pumpkins in each<br />

of the 8 rows on one side of the road <strong>and</strong> 9 rows on<br />

the other side. Add them up.<br />

10+10+10+10+10+10+10+10 = 80<br />

10+10+10+10+10+10+10+10+10 = 90<br />

80 + 90 = 170 pumpkins<br />

Plan 2 Use counters to represent rows.<br />

Decide what facts you know. Plan what you will do <strong>and</strong><br />

in what order. Use your plan to solve the problem. Then<br />

check your solution to make sure it makes sense.<br />
