COMPARATIVE THINKING
Compare a number on the right of the equal sign with a number on the
left of the equal sign. Let’s compare 55 to 51.
55 is 4 more than 51
You have to add 4 to 51 to equal 55
Now you will compare the 23 to the 24.
23 is 1 less than 24
Look at the little numbers above 51 + 24. Do the math. 4 – 1 = 3
+4
-1
55 + 23 = 51 + 24
This equation is FALSE. If the answer were 0 it would be a TRUE equation.
Use comparative thinking to decide which
equation is TRUE. Do NOT solve.
a. 15 + 70 = 21 + 68
b. 25 + 43 = 28 + 40
c. 60 + 36 = 30 + 65
d. 500 = 200 + 301
Which statement explains this equation?
14 + 28 = 18 + 24
a.
b.
c.
d.
The
This
This
This
answer is 14 + 28 = 42 so 18 + 24 = 42. the answer is 42
is a true statement because they are the same numbers
is true because they just switched the digits in the ones place
statement is false because the numbers are not the same
Which statement explains this equation?
97 + 56 = 95 + 67
a.
b.
c.
d.
This
This
This
This
is
is
is
is
a true statement because they used all the same digits
true because 97 is more than 56 and 95 is more than 67
true because they mixed up the digits
false because 97 is 2 more than 95 and 67 is 11 more than 56
This is a balancing equation.
14 + 50
=
60 + ?
This is a balancing equation.
36 + 72
=
81 + ?
This is a balancing equation.
42 + 57
=
? + 93
