## Grade 2 ~ Third Trimester 2018-2019

## March 14th is Pi Day!

**March 14th is also the birthday of famous mathematician and scientist ALBERT EINSTEIN.**Pi is special because it’s a symbol used to describe the relationship (or ratio) between the distance around a circle (circumference) and the distance across the center of a circle (diameter). Consider celebrating Pi Day with your students. Click here for fun facts, videos, and activities.

## The Final 1/3 ... of Grade 2

**In the last trimester, second graders will begin to develop their conceptual understanding of metric measurement, learn to analyze and interpret data, plus explore the world of geometry and fractions. **Considering fractions is the last Grade 2 topic, you may want to check out the following lessons found in the “Getting Ready for Grade 3” section of your GO Math! Planning Guide.

**Lesson 18: Fraction Models: Thirds & Sixths**

**Lesson 19: Fraction Models: Fourths & Eighths (How to create a Fraction Kit)**

**Lesson 20: Compare Fraction Models**

Ask your building math specialist to visit and demonstrate the **Fraction Cover Up** game too. Giving students the opportunity to preview third-grade material could prove to be academically beneficial.

## 20 Days of Number Sense & Rich Math Talk (K-12)

Steve Wyborney (creator of many popular numbers sense routines for K-12), has just finished and released a project that took him 7 months to complete. It's called __20 Days of Number Sense & Rich Math Talk__ - 20 days of lessons that give students a really good opportunity to experience number sense - and to experience very rich math discourse. He leveled the lessons so that they are available and accessible to ALL elementary students.

Included in this project are 4 different activities (and 5 days of each activity). Here is the breakdown:

Days 1-5: Estimation Clipboard

Days 6-10: Splat Activities

Days 11-15: Esti-Mysteries

Days 16-20: Cube Conversations

Your students will LOVE these activities...ask your math specialist if you have any questions or need any assistance.

Have you seen Dan Finkel’s TEDx talk? If not, click here: __Five Principles of Extraordinary Math Teaching__...you will soon be hooked! After obtaining his Ph.D. in mathematics, Dan became dedicated to understanding and teaching the motivation, history, aesthetics, and deep structure of mathematics. Like many of us, Dan has made it his goal to **“give everyone the chance to fall in love with mathematics.” **Check out __https://mathforlove.com/__, where you can find a free lesson library and information about learning through play with games.

## Tiny Polka Dot GAME: The Pyramid Puzzle (NJSLS 2.OA.B.2)

## Fact Fluency ~ NJSLS 2.OA.B2

By the end of the year, grade two students are also expected to know from memory all sums of two one-digit numbers. In other words, grade two students are to fluently add and subtract within 20 using mental strategies (not their fingers). Consider implementing the following games from Dan Finkel's blog __https://mathforlove.com/.__

## Penny, Nickel, DimeRoll the die 7 times. For every roll, you get to take that many pennies, nickels, or dimes. Whoever gets closest to $1 without going over wins. | ## Math Games & Movement Breaks The rules are simple: if the teacher gives the number 10, students stand up. Any other number, they sit down. The trick is, the teacher will say things like “7+3” and “14 – 5” (pick appropriate sums and differences for your students to solve mentally). There are endless variations. Click here for more details. | ## Save 20The goal of the game is to roll as close to (or equal) to 20, without going over. You’ll have four rounds per turn. For the first rounds, roll all five dice. You may save as many as you like, from zero to all. Any dice that are saved may not be re-rolled for the rest of your turn. For your second and third round, roll the dice you haven’t saved. You may save as many of these as you like. For the fourth and final round, roll any remaining unsaved dice. Now score your points. If your five dice form a sum greater than 20, you score 0. If the dice sum to 20 or less, that number is your score for the turn. Play for 9 turns. The winner is whoever has the greatest score at the end of the game. (Play is best with 2-3 players.) |
