Multiplication

I am learning to use Multiplication strategies in level 3.

1.    When Jasmine makes lemonade she uses 6 lemons for every litre of water. How many lemons does she need for

i)     2 litres of water?   12 -  6x2=12 - 6 doubled = 12

ii)    3 litres of water?   18 - 6x3=18 - 6 tripled is 18

iii)   10 litres of water?  60 - 6x10=60

2.   Devinda is doing some baking. When he uses his mum's recipe he can make 8 muffins. When he doubles the recipe he gets 16 muffins. How many lots of the recipe does he need to make

i)     24 muffins?     24x8=? - 10x8=80 - 10x8=80 - 80+80= 160. 8x4= 32 +160= 192

ii)    32 muffins?     32x8=? - 10x8=80 - 80 tripled is 220. 8x2=16+220= 236

iii)   56 muffins?      8x56=? - 8x10=80 - doubled 5 times = 80 doubled is 160. 160 doubled is 320 + 80 = 400. 8x6= 48 400+48=448
