LESSON 2 Constant Hoppers

Professor Peabody studied the behavior of constant hoppers and found several kinds. One is the +3 (plus three) hopper. The +3 hopper always hops 3 units to the right on the number line. Professor Peabody saw a +3 hopper start at 0 and hop four times. Where did it land?

• 

3 + 3 + 3 + 3 = 12 is an addition sentence that describes its trip. 4 × 3 = 12 is a multiplication sentence that describes its trip.

1. A +2 hopper started at 0 and hopped 4 times. It landed on 8. Write an addition sentence that describe its trip.
2. Write a multiplication sentence that describes its trip.

• 
1. A +5 hopper started at 0 and hopped 3 times. Use your desk number line to show where it will land.
2. Write an addition sentence that describes its trip.
3. Write a multiplication sentence that describes its trip.
