Answer Key
Teacher Notes:
This worksheet helps young learners connect the idea of energy to simple robot actions using counting, comparing, and problem solving. Suggested classroom use: small-group lesson, guided practice, independent center work, or partner talk. Learning objectives: identify that robots need energy to work, solve simple addition and subtraction word problems within 10, compare more/less, and think about when a robot needs to recharge. Differentiation: for struggling learners, use counters, finger counting, and teacher read-aloud support; reduce the number of answer choices if needed. For advanced learners, ask students to explain their thinking, create their own robot energy story, or solve the problem two ways. Extension activities: sort pictures of things that need energy, match robots to energy sources, or act out charging and working.
| # | Answer | Explanation |
|---|
| 1 | 2 batteries | 1 and 1 more makes 2. |
| 2 | 1 light | 2 take away 1 leaves 1. |
| 3 | 1 more cube | 3 need in all and 2 are there, so 1 more is needed. |
| 4 | 5 steps | 4 plus 1 equals 5. |
| 5 | The robot with 5 power stars | 5 is more than 3. |
| 6 | 4 batteries | 2 plus 2 equals 4. |
| 7 | 5 energy dots | 6 take away 1 leaves 5. |
| 8 | 3 spots | 7 total spots minus 4 full spots leaves 3 empty spots. |
| 9 | 6 power stickers | 3 and 3 make 6. |
| 10 | 6 minutes | 8 take away 2 equals 6. |
| 11 | Yes, they have the same amount. | Both robots have 4 battery bars. |
| 12 | 3 batteries | 1 plus 2 equals 3. |
| 13 | 3 lights | 5 take away 2 leaves 3. |
| 14 | 3 more bolts | 4 needed total, 1 already there, so 3 more are needed. |
| 15 | 5 sun beams | 2 plus 3 equals 5. |
| 16 | 4 power chips | 7 take away 3 leaves 4. |
| 17 | 4 battery cells | 6 take away 2 equals 4. |
| 18 | 4 spaces | 9 minus 5 equals 4. |
| 19 | 8 sparkles | 4 plus 4 equals 8. |
| 20 | 9 power points | 10 take away 1 leaves 9. |
| 21 | 5 charging cords | 3 plus 2 equals 5. |
| 22 | 4 stickers | 8 take away 4 equals 4. |
| 23 | 4 more units | 6 needed total, 2 are already there, so 4 more are needed. |
| 24 | 8 energy beads | 5 plus 2 plus 1 equals 8. |
| 25 | 2 battery bars | 6 take away 2 take away 2 leaves 2. |
| 26 | 8 energy lights | 3 plus 5 equals 8. |
| 27 | Yes, it has enough energy. | The robot needs 7 points and it has 7 points. |
| 28 | 7 power beads | 9 take away 2 equals 7. |
| 29 | 5 batteries | 4 plus 4 equals 8, and 8 take away 3 equals 5. |
