Shawn and Janet build robots. All of their robots are either red or yellow. How can you add the robots?
Answer:
Explanation:
Shawn and Janet build robots
All of their robots are either red or yellow
There could be 6 red robots and 4 yellow robots
The addition equations will be 6 + 4 = 10 or 4 + 6 = 10.
Ask children to color some of the robots red and some of the robots yellow. All the robots should be either red or yellow. Have children write an equation to show adding the red robots and the yellow robots. Then have children write an equation to add the yellow robots and the red robots. What do you notice about the two sums?
