### Unit4 components

1. 1. Components of Number Sense Overview Unit 4
2. 2. What’s the “Big Idea”? <ul><li>Multiple authors recommend that teachers utilize the “Big Ideas” in their instruction. </li></ul><ul><li>Generally authors present the “Big Ideas” as lesson specific. </li></ul><ul><li>Often lessons are disconnected from each other and / or focus on one “Big Idea” for that lesson. </li></ul><ul><li>Big Ideas Revisited </li></ul><ul><li>We use the “Components of Number Sense” to connect every part of the curriculum in almost every lesson, thus, making our lessons more powerful and more efficient. </li></ul><ul><li>Outcome equals stronger teachers and stronger math students . </li></ul>
3. 3. How does this fit with the NCTM? <ul><li>The NCTM utilizes a strands curriculum </li></ul><ul><li>The Components of Number Sense are not in conflict with the NCTM strands. </li></ul><ul><li>The Components enable teachers to build true understanding of the mathematical strands. </li></ul><ul><li>This helps maintain and build connections for the way students think about mathematics. </li></ul>
4. 4. NCTM Strands Without Number Sense Number & Operations Measurement Geometry Data Analysis and Probability Algebra
