fraction rules
Fractions enVision Topic 9PA Assessment Anchor M5.A
Grade 5/6 Anchor Glossary
BEFORE you can:
compare fractions OR
add fractions OR
subtract fractions YOU MUST RENAME them
example: ½ and ¼ LCM: 4
products of 2: 2, 4 ½ = 2/4
products of 4: 4, 8 ¼ = ¼
2/4 > ¼
* find the LCM
* rename all fractions using LCM as new denominator
12
equivalent fractions
