Week 7 problem solving - Alfred

Today we were given (Room 7) a maths problem to solve through out the weekend and today (Monday) we had to solve the problem with the class. I was given that task with another bunch of class mates. We had to show how we worked out the problem with a strategy. My strategy was .......... Shown bellow.

The Strategy that I used is called Doubling a number and halving another number. There is three answers to this Problem. Shown below

Shown in numbers and Words
1. 174 / 2 = 87 x 5 = 870
For the veggies I halved 174 that gave me 87, 87 x 5 = 870

Shown in numbers and Words
2. For the meat I halved  174 to make 87 then doubled 3 to make 6. 87 x 6 = 522.
174 / 2 = 87 3 x 2 = 6. 87 x 6 522

Shown in numbers and Words
3. For the fruit I doubled and halved 174 and 4 to 87 and 8 which = 696
174 / 2 = 87. 4 x 2 = 8. 87 x 8 = 696

Alfred you are progressing very well in Mathematics. You consistently try different strategies and do a good job at sharing your Mathematical thinking. Well done and keep it up.
