### Highlighting some Math Ideas and Strategies

## 86 PAGES OF MATH VOCAB

## 2nd - 9 WEEKS (WEEK 7) - 3RD GRADE SKILLS BLOCK

* Wrap up addition /subtraction fact fluency- Identify students who have not met expectations and need extra support-create a plan to meet their needs

* Continue Decomposing Facts

* Continue Multiplying by 10 and multiples of 10 (20,30,40,etc…) Do NOT use the phrase “put a 0 on the end” it forms misconceptions in student understanding

* **The Relationship Between Multiplication and Division – See Unit 5 pg 148 & 175** – Problems can be solved by either operation if you can justify your thinking…

## 2nd - 9 WEEKS (WEEK 7) - 4TH GRADE SKILLS BLOCK

* Multiplication Fact Fluency-each student is working on activities to support their individual goal

* Investigation Unit 4 Session 1.1: Measurement Benchmarks – Create anchor charts of items that are about 1 cm, 1 yd, etc… Important note: Linear measurements are recording the measurement of a 1-d object or part of the object. This is important when differentiating between area and perimeter. Perimeter measures length, just one dimension. Area measures the space in the middle which has 2 dimensions, length and width. Make sure to do the discussion about “Why do our measurements differ?”

* Repeat Last Equation Wins or Racing Fractions from daily lessons

## POSTER PROBLEMS "6 PHASES"

## 1. Launch

Teachers set the stage by leading an introductory discussion that orients students to the context of the problem.

## 2. Pose a Problem

Teachers introduce a mathematical way of thinking about the context and engage students in a preliminary approach that opens the door to the workshop phase.

## 3. Workshop

The workshop starts with a more challenging and more open-ended extension of the problem. In teams, students plan and produce mathematical posters to communicate their work.

## 4. Post, Share, Comment

## 5. Strategic Teacher-Led Discussion

## 6. Focus Problem: Same Concept in a New Context
