Questions:
1.Annie has been asked to calculate 1.7 + 6 ÷ 2. She claims that the answer is 3.85. Do you agree? Explain why or why not.
Answer: Annie is wrong because 4.7 is the right answer. This is how I got it.
1.7 + 6 ÷ 2 =
1.7 + 3 =
4.7=
2.Put brackets in the following expression to get the largest value possible. What problem solving strategy did you use?
Answer: I used multiplication and division.
Multiplication:
( 3 x 2.8 ) + 6.4 ÷ 4 =
8.4 + 6.4 ÷ 4 =
8.4 + 1.6 =
10 =
Division:3 x 2.8 + ( 6.4 ÷ 4 ) =
3 x 2.8 + 1.6 =
8.4 + 1.6 =
10 =
3.Create a problem that could be solved using the following expression. 2.5 + 1.25 + 5 x 1.6
Problem: Nicole went out to buy candies. The gum cost $1.25, the chocolate cost $2.5 and 5 lollipops cost $1.6 each. Nicole has $13, does she have enough money?
