2nd Grade Math Expressions

October 5, 2010Laura ChamblessDr. Monica Hartman

Agenda

1. Introduction to Common Core State Standards

2. Digging into your end of year assessment data

3. Deeper look at number sense units4. What you are going to focus on back in class?

2nd Year In Program/Intro Write on a sticky note

One thing you noticed about teaching Math Expressions so far this year.

Share with someone that is not in your building. Stand back to back when you are done sharing.Partner with shortest hair reports out to group.

Common Core Standards

Mathematics Document– Mathematical practices– Grade level instructional focus– Grade level overview w/practices box– Grade level standards

Looking at Data1. Look over end of year Benchmark Assessment

– Find questions which students are at advance level (star) CELEBRATE!

– Find questions which students are at basic level (B)– Find questions which students are at below basic level (BB)

2. Look at the End of Year Assessment - Response Frequency Report (Item Analysis) to find GLCE.

3. Use the CC Aligned to GLCE document to look at Basic (B) and Below Basic (BB) items. Find where it is taught in your MX book.

Unit 1: Strategies• Break-Aparts

– Partner Houses– Math Mountains

• Count On Strategies (+/-) to find Totals/Partner– Count all using pictures– Count on using number and pictures– Count on using fingers

• Make a Ten Strategies

Unit 3: Problem Types

1. Change Plus Problems/Change Minus Problems2. Collection Problems: Put Together or Take Apart3. Collection Problems: Static/No Action4. Group Name Problem5. Comparison Problems

See Teaching Notes: math background on problem type

• Last year our school had 5 computers in the library. They bought some more over the summer. Now there are 12. How many computers did they buy over the summer?

• Understanding the problem– Read the problem aloud and have a few

volunteers retell the problem in their own words.• Act it out

– Drawings, Equations, Math Mountains - label drawings

Practice• Use Teaching Notes for background

information on problem type.

• Complete Understanding Story Problems A– First by yourself– When elbow partner is done- compare answers– Complete B-D the same way

• Use teacher manual to help (unit 3)

Addition/Subtraction MethodsUnit 5

• Review Accessible Algorithms for Addition/Subtraction

• Practice Sheets

Formative Assessment

What will you focus on when teaching Math Expressions units 1, 3, or 5? Why
