DescriptionIn the last of three clips in a first grade classroom, Jeff, Milin and Jamie begin by reading problem 4. Jeff, without referring to the stones or cubes, immediately states that Grandpa would have six chickens and the other two children agree. Similarly, after reading problem 5, Jeff states that Catherine would wash two dishes. Jamie then reads problem 6. Each child counts out six stones and four stones, combine the two sets and state that the rabbit would take ten jumps. They record each answer as an addition or subtraction number sentence. When they are finished recording their answer for problem 6, Jamie announces to teacher Angela Marinaro that they are done. She asks them to revisit each of the three problems in turn and agrees with their solutions to the first two. When the children tell her that their answer to problem 6 is ten, Ms. Marinaro asks them to reconsider the problem and leaves the table. The boys, after rereading the problem, state that the answer should have been two and all three children erase their earlier solution and replace it with 6 - 4 = 2.
Statement of problem 4:
Dad has 3 chickens. If Grandpa sells 3 chickens, he will have as many as Dad. How many chickens does Grandpa have?
Statement of problem 5:
Eric washed 5 dishes. Eric washed 3 more dishes than Catherine. How many dishes did Catherine wash?
Statement of problem 6:
The kangaroo jumps 6 times. If the rabbit jumps 4 more times, it will have jumped as many times as the kangaroo. How many times did the rabbit jump?
