Multiplication Strategy: Doubling and Halving

We can simplify some multiplication problems using doubling and halving.

1. Use the strategy of doubling one factor and halving the other to help simplify and solve the following problems: Example: 5 x 16 = 10 x 8 = 80 or 5 x 16 = 10 x 8 = 20 x 4 = 80

a) 5 x 68 = 350

b) 3 x 16 =  48

c) 16 x 30 = 480

d) 18 x 40 = 720

e) 35 x 20 = 700

f) 25 x 16 = 400

g) 50 x 24 = 1400

h) 500 x 28 = 14,ooo

2. Does this strategy always work? No only on even and odd not just odd

Explain when the strategy of doubling and halving is useful to simplify a multiplication problem.

This is what we did for maths and I learnt to double and halving





 
This is the writing i did this week and i learnt that the mountains play apart in a storm.
This is the reading follow up that we had to complete this week.  I refreshed my knowledge on this which we had covered last year.



 
This is the other maths that we had to do we had to double and halving.  This strategy is a lot easier than I thought it was going to be.

Week 7 reflection

This is what i was learning in maths we are halving  and multiplying
 
This is my literacy that I did this week  in class
we had to make a slide about the book  

Reflection week 6

this is what i am learning in mahts

Welcome to 2016!

Hi bloggers
