**Title:** Factortris

**Description:**
This interactive game requires students to create a rectangle with area of the number given.

**Standard(s): **

[MA2013] (3) 21: Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units). [3-MD6]

[MA2013] (3) 22: Relate area to the operations of multiplication and addition. [3-MD7]

[MA2013] (3) 25: Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. [3-G2]

[MA2013] (4) 10: Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. [4-NBT5]

[MA2013] (4) 21: Apply the area and perimeter formulas for rectangles in real-world and mathematical problems. [4-MD3]

[MA2013] (5) 9: Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. [5-NBT6]
