  11. Question: What is rounding? Answer: To give the closest value of a number using multiples of 10. Third Grade NBT.A.1 rounding Gesture: Hold up thumb and index finger as if showing something small. (closest value) Move finger across front of body as if it was hopping. (multiples) Hold up 10 fingers.

  12. Question: What is data? Answer: Information we collect. Third Grade MD.B.3 data Gesture: Draw tallies in the air.

  13. Question: What is a bar graph? Answer: A graph using bars to show data. Third Grade MD.B.3 bargraph Gesture: Put right arm straight up, bend the left at the elbow so it is parallel to the right. (bars) Draw tallies in the air. (data)

  14. Question: What is a picture graph? Answer: A graph using pictures to show data. Third Grade MD.B.3 picturegraph Gesture: Pretend to take a picture. Draw tallies in the air. (data)

  15. Question: What is a line plot? Answer: A number line showing data. Third Grade MD.B.3 line plot Gesture: Draw a line in the air. (number line) Draw tallie marks in the air. (data)

  16. Question: What is a multiple? Answer: The numbers we say when we skip count. Third Grade OA.A.3 multiple Gesture: Make a “hopping” motion with your index finger moving from right to left.

  17. Question: What is multiplication? Answer: Multiplication is putting together equal groups. Third Grade OA.A.3 multiplication Gesture: Cross arms like an X. (multiplication) Clasp hands together. (putting together) Put one arm horizontal over the other like an equal sign. (equal groups)

  18. Question: What is a factor? Answer: The numbers multiplied together to get a product. Third Grade OA.A.1 factor 3x5 = 15 factors Gesture: “Flash” 5 fingers on one hand then the other. (numbers) Cross arms like an X. (multiplied)

  19. Question: What is a product? Answer: The answer to a multiplication problem. Third Grade OA.A.1 product 3 x 5 = 15 product Gesture: Point index fingers, one on chin, the other a little lower. Then point them in a forward direction away from chin. (Sign language for “answer”.) Then cross arms like an X. (multiplication)

  20. Question: What is division? Answer: Division is breaking a set into equal groups. Third Grade OA.A.3 division 2 4 Gesture: With palms together, “slice” hands downward. (division) Make a breaking motion as if breaking a twig. (breaking a set) Put one arm horizontal over the other like an equal sign. (equal groups)
