2. Common Core State Standards ▪ Common Core – Organized by grade level math topic – These primarily guide instruction ▪ Mathematical Practice Standards – Intended to develop “mathematical thinkers” – These are interwoven in all lessons and in all grades

3. Math Practice Standards ▪ Making sense of problems and persevere in solving them ▪ Reason abstractly and quantitatively ▪ Construct viable arguments and critique the reasoning of others ▪ Model with mathematics ▪ Use appropriate tools strategically ▪ Attend to precision ▪ Look for and make use of structure ▪ Look for and express regularity in repeated reasoning

4. Four Critical Areas in 3 rd Grade ▪ Multiplication and Division strategies for multiplication and division within 100 ▪ Developing an understanding of fractions ▪ Understanding arrays and area ▪ Analyzing two-dimensional shapes

5. Starting with Multiplication ▪ Common Core Standard Operations and Algebraic Thinking.7: Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division. ▪ Other Strategies include: – Distributive Property- Associative Property – Commutative Property- Number Line – Repeated Addition- Skip Count – Array- Equal Groups – Use a times table chart

6. Strategies of Multiplication

8. Commutative Property ▪ You can change the order of the factors and the product will stay the same. ▪ Example: 5 x 6 = 307 x 6 = 42 6 x 5 = 306 x 7 = 42

9. Associative Property ▪ You can change the grouping of the factors using parentheses and the product will stay the same. ▪ Example: 4 x 3 x 2 = 24 (4 x 3) x 2 = 24

10. Distributive Property ▪ To multiply a sum by a number, you must by multiply each addend by the number and add the products. ▪ Break up an unfamiliar fact into a fact that they know well. – 7’s – 5 +2 – 8’s – 5+3, 2+2+2+2 ▪ Example: 7 x 4 (5 + 2) x 4 (5 x 4) + (2 x 4) 20 + 8 = 28
