Draw two different ways to show 1/2 with different denominators.
Examples: 4/8, 3/6, 6/12, etc.
Teacher will check answers as they can vary.
Check all that are equivalent to 7/12:
a. 6/12 + 1/12
b. 1/12 + 1/12 + 1/12 + 1/12 + 3/12
c. 1/12 + 4/12 + 1/12
d. 3/12 + 5/12 + 1/12
A and B
1/6 x 8 =
8/6 which is
1 2/6 or 1 1/3
Solve to tell whether the statement is true or false.
128 + 546 + 103 = 21 x 37
True! Both equal 777
The first term of a pattern is an odd number. The rule is add 13. Will the 4th term be odd or even? Explain your reasoning.
5 + 13 = 28
28 + 13 = 41
41 + 13 = 54
54 + 13 = 67
Fourth term will be odd, because every other number will be odd and every other will be even. The 1st and 3rd numbers are even and the 2nd and 4th numbers will be odd.
Draw 2/3, 1/2, and 2/6. Then, put them in order from least to greatest.
**hint use drawings to make equivalent fractions**
2/6, 1/2, 2/3
3/8 + 6/8 =
You have to regroup!
3 + 6 = 9
9/8 is equal to 1 1/8
2/8 x 19 =
38/8
which is 4 6/8 or 4 3/4
Which of the following statements are true:
