Hally 1000 – 4, 1000 – 1 https://mediaplayer.pearsoncmg.com/assets/0156_iPad Question Part 1 Explain what Hally is demonstrating in the first part of the interview when she is subtracting with zeros. Part 2 The interviewer asked Hally if she could solve 1000 minus 1 a different way and she said, “I don’t know.” Based on what you have learned about invented strategies, what method would have been effective for her to use with these subtraction problems. Part 3 In the second part of the interview, Hally is adding using the procedural addition algorithm. Explain what she is demonstrating about her knowledge of place value. Part 4 Hally added 286 + 149 with the standard algorithm. What invented strategies would be beneficial for her to use with this type of problem?
