Solving problems like 35 + ? = 67

TASK... Copy this onto your blog, solve the problems and reflect on how you solved them.

W.A.L.T... solve problems like 35 + ? = 67

24 + ? = 36 34 + ? = 56 37 + ? = 57 44 + ? = 78 45 + ? = 66

14 + ? = 44 43 + ? = 56 34+ ? = 68 44 + ? = 77 22 + ? = 59

I solved these problems by...

60 + 40 = 100 20 + 80 = 100 90 + 10 = 100 30 + 70 = 100

100-30= 70 100-40= 60 100-90= 10 100-70= 30 100-80= 20

95 + 5 = 100 65 + 35= 100 55 + 45 = 100 35 + 65 = 100

100-35= 65 100-75= 25 100-45= 55 100-25= 75 100-85 = 15

CHALLENGE

89 + ? = 100 72 + ? = 100 59 + ? = 100 47 + ? = 1000

TASK...
Highlight these problems and copy into a new post on your blog.
1/4 of 16= 1/4 of 12= 1/4 of 20 = 1/4 of 8=
1/3 of 9 = 1/3 of 12 = 1/3 of 15 = 1/3 of 18=
1/5 of 15 = 1/5 of 25 = 1/5 of 30 = 1/5 of 35 = (clue-ask yourself "How many fives in..?")
CHALLENGE...
If 1/3 of 9= then 2/3 of 9 is
If 1/5 of 15= then 2/5 of 15 is
