90
I know that this
90 triangle is half of a
square
90
45
When the right angles of the
square get cut in half they both
have to be 45.
This looks like 5 and ¼ or ½
This looks like 4 and 3/4
My best guess for this one is 3/4

I know that an EQUALateral
triangle has 3 sides that are all
the same length.

If the 3 sides are all the
same length then the
problem is 18 / 3 = 6
Or I can think 10 x ____ = 50
I’m Francine
and I’m 5 years
older than Mark
We’re using the letter M because
it’s short for Mark.
I’m Mark and
I’m 5 years
younger than
Francine.
M+5 years will be the age of
Francine!
Most of the time I
would round the
numbers to make
guessing and checking
easier. This time I’
going to be sneaky!
119,156 ends in a 6.
That means that I can
pick the last number of
3 of the state and add
them to see if the
number ends is 6.
Wisconsin ends 4.
Vermont ends in 9 and
Illinois ends in 3.
4+9+3=16.
Let’s check: 54,314
+9,249+55,593 =
119,156
