Common Core State Standards Mathematical Practices

Common Core State StandardsFor Mathematics • Goals today: • Become familiar with the Mathematical Practices and what they mean and look like in instruction • Addition Strategies: Introduction and Practice • Number Talks: Demonstration, Video, Planning

Common Core State StandardsFor Mathematics • Clear and specific standards designed to replace curriculums that are “a mile wide and an inch deep” • Based on research about how students learn mathematics • Focus on students understanding the math they do

Mathematical Practices • 1. Make sense of problems and persevere in solving them. • 2. Reason abstractly and quantitatively. • 3. Construct viable arguments and critique the reasoning of others. • 4. Model with mathematics. • 5. Use appropriate tools strategically. • 6. Attend to precision. • 7. Look for and make use of structure. • 8. Look for and express regularity in repeated reasoning.

Mathematical Practices: Individual Task • Read the mathematical practice assigned. • Make notes about what the words mean to you and what it looks like in the classrooms for your grade span. Be ready to share in 5 minutes.

Mathematical Practices:Group Task • Using your collective information, create a poster to illustrate the practice and what it looks like at your grade levels. • Leave room for others to add ideas. • Label the poster with the Mathematical Practice and the Grade Span. • Post your charts so they are spaced around the room.

Mathematical Practices:Group Task • Expert groups: • Count off within your group A, B, C, etc. • As, Bs, Cs, etc. will walk around together and view each poster. • The ‘expert’ who helped to make the poster shares the Mathematical Practice with the group. • Add any relevant information to each poster that your group discusses.

Common Core State Standards “Standards for Mathematical Content are a balanced combination of procedure and understanding.” Common Core State Standards, p. 2

Common Core State Standards “In short, a lack of understanding effectively prevents a student from engaging in mathematical practices.” Common Core State Standards, p. 2

Common Core State Standards • Addition Strategies: • Branching • Decomposing • Partial Sums • Bridging

Common Core State Standards • Branching Strategy: • 9 + 7+ 1 + 8 + 6 + 8 = ☐ • 78 + 56 = ☐ • 262 + 425 = ☐

Common Core State Standards • Decomposing Strategy: • 8 + 7 = ☐ • 56 + 35 = ☐ • 262 + 425 = ☐

Common Core State Standards • Partial Sums Strategy: • 56 + 35 = ☐ • 768 + 597 = ☐

Common Core State Standards • Bridging Strategy: • 57 + 35 = ☐ • 68 + 59 = ☐ • 397 + 286 = ☐

Common Core State Standards Task: Using the construction paper, make a poster for each strategy that clearly demonstrates use of the strategy. Utilize strategy hand-out. Hang posters back in your classroom for student reference once the strategy is introduced.
