#### What educators are saying

Great resource! I bought this about five years ago and still use it! It's a great tool, and highly engaging!! My kids loved it.

### Description

5.3K teaches children to add and subtract positive rational numbers fluently. This kit provides tons of practice (enough for several sessions, probably) adding and subtracting fractions with unlike denominators and decimals, sometimes in the same word problem or algorithm.

Included are 34 problems which can all be added and/or subtracted (so 68 problems total), Pow! game cards, ideas for instruction of the TEK, ideas for differentiation, answer keys, etc.

If you find this product helpful, be sure to click the "Follow Me" link above, as I am trying to add products for all of the new fifth grade TEKS this year, with fourth grade to be added next year.

Happy teaching!

### Standards

to see state-specific standards (only available in the US).
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, 𝘢/𝘣 + 𝘤/𝘥 = (𝘢𝘥 + 𝘣𝘤)/𝘣𝘥.)
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
