10. Add and subtract fractions and mixed numbers with unlike denominators, using fraction equivalence to calculate a sum or difference of fractions or mixed numbers with like denominators.

[MA2019] (5) 12 :

12. Apply and extend previous understandings of multiplication to find the product of a fraction times a whole number or a fraction times a fraction.

a. Use a visual fraction model (area model, set model, or linear model) to show (^a/_b) x q and create a story context for this equation to interpret the product as a parts of a partition of q into b equal parts.

b. Use a visual fraction model (area model, set model, or linear model) to show (^a/_b) x (^c/_d) and create a story context for this equation to interpret the product.

c. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.

d. Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths to show that the area is the same as would be found by multiplying the side lengths.

This activity is an exploration of mixed numbers, improper fractions, multiplying fractions by a whole number, and adding fractions with unlike denominators. The students will create a digital design using virtual pattern blocks. Counting the hexagon as one whole, the students will multiply the fractional pieces of their design and then use a blank pattern block template to add fractions with unlike denominators and find the total value for the picture.

This activity results from the ALEX Resource Development Summit.
