Step 1: Identify the starting amount. Leo has 33 pieces of candy.
*
Step 2: Identify how much is taken away. He gives away 14 pieces.
*
Step 3: Subtract the amount given away from the total.
* $33 - 14 = ?$
* First, subtract 10 from 33 to get 23. Then subtract 4 more.
* $23 - 4 = 19$.
*
Check: $19 + 14 = 33$. The math is correct.
2) Anne Marie's Bike Ride

*
Step 3: Subtract the time passed from the total time to find out how much is left.
* $41 - 17 = ?$
* Think: $41 - 10 = 31$. Then $31 - 7 = 24$.
*
Check: $24 + 17 = 41$. The math is correct.
3) Lisa's Invitations
