Document Summary

Do on answer sheet #1: illustrate each step of the standard algorithm below showing what base ten blocks you would use. You may use simplified sketches of the blocks, such as: Use the take-away interpretation of subtraction do not lay out blocks for the quantity that will be removed at the end: draw appropriate diagrams to illustrate each step of the standard algorithm for. Give your final answer as both an improper fraction and as a mixed number. Solve the subtraction problem 10 62/3 using two different arithmetic algorithms. (drawing a picture may help you, but it does not count as an algorithm. : consider the subtraction problem 5 3. Give an example (a word problem) of how to interpret this expression as the difference of two numbers. Explain without using common denominators, decimals, or cross- multiplication: identify each statement as true or false. 6 + 7 = 7 + 6 is an example of the commutative property.
