**Common Core State Standards for Mathematics**

CCSS.Math.Practice.MP1Make sense of problems and persevere in solving them.

CCSS.Math.Content.4.NBT.B.5Multiply 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 ar

CCSS.Math.Content.5.NBT.A.3aRead and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).

CCSS.Math.Content.3.MD.C.7bMultiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

CCSS.Math.Content.3.G.A.2Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.

CCSS.Math.Content.3.NF.A.1Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

CCSS.Math.Content.3.NF.A.3cExpress whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.

CCSS.Math.Content.4.NF.B.4aUnderstand a fraction a/b as a multiple of 1/b.

CCSS.Math.Content.4.NF.C.5Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.

CCSS.Math.Content.4.NF.C.6Use decimal notation for fractions with denominators 10 or 100.

CCSS.Math.Content.5.NF.B.3Interpret 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

CCSS.Math.Practice.MP4Model with mathematics.

CCSS.Math.Practice.MP5Use appropriate tools strategically.

CCSS.Math.Practice.MP7Look for and make use of structure.
