Math Night – Session 2 Thursday February 5, 2015 Second Grade Terri Buscemi - Math Specialist Mulready and Farley Elementary Schools Agenda • 6:00 – 6:15 – Addition and Subtraction Strategies • 6:15 – 6:45 – Foundations of Multiplication and Division (Module 6) • 6:45 – 7:00 – Activities to do at home to support concepts in Module 7 Make a hundred strategy 256 + 399 = • Choose a number to get to the closest hundred • Create a number bond with the other number • Make a new equation • Solve the simplified equation 256 +399 ^ 255 1 255 + 400 = 655 Make a hundred strategy 225 + 280= • Choose a number to get to the closest hundred • Create a number bond with the other number • Make a new equation • Solve the simplified equation 225 +280 ^ 215 10 215 + 290 = ^ 205 10 205 + 300 = 505 Compensation Strategy 256 – 199 = • Make a tape diagram • Add to the subtrahend (the number you are subtraction) to make a number you can subtract easily, add the same amount to the minuend • Write the simplified equation • Solve +1 +1 256 199 • 257 – 200 = 57 Module 6: Foundations of Multiplication and Division During this module the students will: • Form equal groups with manipulatives and drawings • Create arrays and relate it to repeated addition • Understand the meaning of even and odd numbers Form equal groups with manipulatives and drawings Mayra sorts her socks by color. She has 4 purple socks, 4 yellow socks, 4 pink socks and 4 orange socks. Draw groups to show how Mayra sorts her socks. Then write an addition sentence to match. How many socks does Mayra have in all? 4 + 4 + 4 + 4 = 16 Create arrays and relate it to repeated addition and tape diagrams Mrs. Buscemi arranges the desks into 4 rows of 5. How many desks are in her room? 1. Draw a picture 2. Create a number sentence 3. Make a tape diagram 4. Write a statement Mrs. Buscemi’s room has 20 desks. 4 + 4 + 4 + 4 + 4 4 4 4 20 4 4 Decomposing a rectangle using square tiles Construct a rectangle with 4 rows of 5 tiles. What repeated addition problem will tell you how many tiles there are? How can we decompose the rectangle to make 2 equal parts? Use the ruler to break your rectangle into 2 parts. 4 rows of 5 2 rows of 5 2 rows of 5 5+5 = 10 5+5 = 10 Understand the meaning of even and odd numbers Take out 8 tiles. Is 8 an even or odd number? There are 4 pairs of 2 Take out 15 tiles There are 2 groups of 2 Is 15 an even or odd number? There are 7 pairs of 2 with one left over Prove it! Prove it! There are 2 groups of 7 with one left over Activities to do at home to support concepts in Module 7:Problem Solving with Length, Money and Data 1.Get to a dollar – need coins and a die Roll the die and collect that many cents (ie roll a 3, take 3 pennies) Continue to roll the die and collect the correct amount of money, trading as you go along. (ie you have 14 cents. You roll a 6 and collect 6 pennies, you will need to trade 10 pennies for a dime) The games ends when someone has a dollar. 2. Lose a dollar – need coins and a die Same as above, but this time you start with a dollar and give back what you roll. 3. Look at graphs and data tables in the newspaper and online 4. Use a ruler to measure using both inches and centimeters.
