# Kyrene 3rd Grade Family Math Page

• Semester 1 Focus - Fall/Winter 2020

Represent and solve problems involving whole number multiplication and division.

Multiply and divide within 100.

3.OA.A.1 - Interpret products of whole numbers as the total number of objects in equal groups (e.g., interpret 5 x 7 as the total number of objects in 5 groups of 7 objects each).

3.OA.A.4 - Determine the unknown whole number in a multiplication or division equation relating three whole numbers For example, determine the unknown number that makes the equation true in each of the equations 8 x  = 48, 5 =  ÷ 3, 6 x 6 =  .

3.OA.C.7 Multiply and divide within 100. Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.

Semester 2 Focus - Winter/Spring 2021

Develop understanding of fractions as numbers.

3.NF.A.1  Understand 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.

3.NF.A.3b Develop understanding of fractions as numbers.

3. Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

b. Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., by using a visual fraction model.

# Skip Counting Practice

• In third grade, multiplication and division concepts are formalized within 100. Skip counting is a skill that connects counting by 2s,5s, 10s, etc. (1st and 2nd grade) to repeated addition (2nd grade) to multiplication (3rd grade). Third graders need multiple experiences with numbers and number patterns to become flexible. Just a few minutes a day practicing skip counting will help lay a solid foundation for multiplication.

Below are links to short videos to practice skip counting using visual dot patterns.  Each video is less than 2 minutes long. We encourage you to start practicing with familiar numbers like 2s, 5s, and 10s, then work up to more challenging patterns like 3s, 4s, and 6s, then finally 7s, 8s, and 9s.

Linked is a 100 chart to print at home to help students visually see patterns when they are skip counting within 100.

# Multiplication and Division Fact Family Cards

• Triangle multiplication & division fact flashcards will be provided to each third grader in Kyrene to practice multiplication and division at home.

These cards will be sent home to all third graders with second quarter materials.

Directions for Using Figuro Flash Cards

• To practice multiplication, place your thumb over the underlined number on the triangle and hold the card for your child to see. Your child should tell you the product (result of multiplying) of the remaining numbers at the base of the triangle. In our example, you would cover the 24. Your child would say, “Eight times three equals twenty-four.”
• To practice division, place your thumb over one of the numbers at the base of the triangle and hold the card for your child to see. Let your child tell you a division fact using the remaining two numbers, and then have your child give you the quotient (answer). In our example, you could cover the 8. Your child would say, “Twenty-four divided by three equals eight.”
