I created this set of 40 task cards because I noticed my students needed a lot more experience with using arrays to solve multiplying fraction problems. There are 40 task cards that takes students from basic arrays of whole numbers x whole numbers, to mixed numbers x fractions to story problems.
Please check out the Preview to view most of this resource.
How can I use this product?
Great to hand out to whole class table groups for discussions to an independent math center as the answer key is thorough.
What is included?
1 pdf with 26 pages
* 3 pages of cover/copyright info/notes and standards
* 1 page of a set of 4 blank task cards in case you want to add your own
* 10 pages with four array tasks on each page (landscape)
* 4 page answer key
* 5 pages of student answer sheets
* 3 pages of student tracking sheets
Is this available in a bundle?
Not yet, but I am planning on making an Array bundle.

What standards are addressed?
Common Core Standards
CCSS.Math.Content.4.MD.A.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
Interpret the product (a/b) × q as a parts of a partition of q into b equal parts; equivalently, as the result of a sequence of operations a × q ÷ b. For example, use a visual fraction model to show (2/3) × 4 = 8/3, and create a story context for this equation. Do the same with (2/3) × (4/5) = 8/15. (In general, (a/b) × (c/d) = ac/bd.)
Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.
