Phoebe's maths progress

1. 4x35=(4x30)+(4x5)=120+20=140
2. 3x39=(3x30)+(3x9)=90+27=117
here is division
1.58 divided by 3=19
/ /
30 27
/ /
10 9
so 1o+9=19
19/10/11
112 divided by 8=14
8x =112
you go 8x12=96+8=104+8=112
s0 8x14=112 so 14 is the answer
14/11/11
2/3 of 21=14
21 lollies into 3 groups of 7 so 2/3 of 21 would be 14

  2. Hi Phoebe - I think Roneta means you used the place value strategy where you multiply the tens number and then the ones number.

    You can also do it this way
    Make 39 40
    3 x 40 = 120 but then you have to take 3 away because you added 3 extra on my multiplying by 40 instead of 3.

    Try this one

    3 x 29 = If you are not sure what I mean, come and chat with me . Great to see your post on our blog
