2Nd Grade Math Plans

2nd Grade Math Plans 1st 9 weeks - 5th week

Monday, September 15 - Friday, September 19, 2014 - The student will: 1) Be introduced to the Addition Strategy of the Week: Doubles on Monday. 2) Review how we determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s. 3) Write an equation to express an even number as a sum of two equal addends (only to 20). 4) If students catch on to standard 2.OA.3 quickly, you may use the other days this week to review previous material.

Vocabulary - refer to words from weeks 2,3,4 odd even equation

1 Flipchart Odd Even Using Doubles

Monday - EQ: How do you determine if a number is odd or even?

In this lesson - 1) Introduce the Addition Strategy of the Week: Doubles on Monday. The rest of the week you will do a review of this strategy. You may want to spiral back and review some of the other strategies (this would be a very quick review). Use the Doubles Flipchart (Resource Box). a. Make real world connection: fingers and toes - 5+5, wheels on a car - 2+2, or the eggs in a carton - 6+6. Possible activity: have students make posters making these same connections. b. Create anchor chart to display in the room or in student math journals. c. Have students write equations in their journal then add a rhyming word to help them remember. For example: 4+4=8 that's great 5+5=10 again 6+6=12 that's swell 7+7=14 let's lean d. Use people equations with students. e. Have students complete Double Trouble Addition worksheet (Resource Box)

2) Daily Spiral Review: Complete Week 5 - Day 1 Daily Spiral Review (Resource Box).

Teaching Strategies: 1. Review how you last week determined that a number was odd or even. It may have been by using unifix cubes for the number 12 and making 2 equal stacks of 6 each with no cubes left over. 12 is an even number. Do any students realize that a number that ends in a 2 is always even? What do other even numbers end in? (0,2,4,6, or 8). How about odd numbers? Why is 9 an odd number? Because you pair up cubes, but you have one left over. Do any students realize that a number that ends in a 1,3,5,7 or 9 is an odd number? 2. Show Odd Even Flipchart (Resource Box).

Classwork:  Have students complete Even and Odd worksheet (they will need some type of manipulative-cubes, pattern blocks, counters, etc.) - Resource Box.

 Game - Have students play The Treehouse Game (Resource Box).

2 Homework: Even or Odd House Search worksheet (Resource Box) - have students fill in as many as possible at home OR have students complete Homework - Monday's Math Homework (Resource Box).

Tuesday - EQ: How do you determine if a number is odd or even?

In this lesson - 1) Review the Addition Strategy of the Week: Doubles. Give students the Add Doubles to 10 worksheet (Resource Box) to practice their doubles.

Teaching Strategies: 1. Students not only need to be able to determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s, but students also must be able to write an equation to express an even number as a sum of two equal addends. For example, 8 is an even number because I can pair 8 counters up into groups of 2. Since I do not have any counters left over, I know that 8 is an even number. The equation representing this is 4 + 4 = 8.

a. Also, if students can make a rectangular array out of a number of counters, that number is even. 8 is

b. Use unifix or snap cubes or base ten blocks to have students discover this about rectangular arrays and even numbers. If a number is odd, you cannot make a rectangular array.

3 Classwork: Teacher choice or Envision Math Textbook Lesson 5-6

Summarizing Strategy: In journal, have students tell you whether 14 is an even or odd number and for them to prove it.

Homework: Have students complete Tuesday's Math Homework (Resource Box).

Wednesday - EQ: How do you determine if a number is odd or even?

In this lesson - 1) Review the Addition Strategy of the Week: Doubles. Give students the Add Doubles to 20 worksheet (Resource Box) to practice their doubles.

Teaching Strategies: 1. Review 2.OA.3 standard. Students may need more practice with manipulatives.

Classwork: Have students play the game Jump Start Math - Even or Odd (Resource Box) and/or give students Even and Odd worksheet (Resource Box) and have them color the even numbers one color and the odd numbers another color.

Homework: Have students complete Wednesday's Math Homework (Resource Box).

Thursday - EQ: How do you determine if a number is odd or even?

In this lesson - 1) Review the Addition Strategy of the Week: Doubles. Have students play the game I Have, Who Has? Double Facts by Jed Dearybury (Resource Box) to practice their doubles. You may need to help students with problems like 100 + 100, 200 + 200, 300 + 300, 400 + 400, but the other ones make this game worth playing.

Classwork: Choose from: Formative Assessment - 2.OA.3 - Task (Resource Box), Even and Odd (pages 1,2), Challenge Sheet is Even and Odd (page 3), and Even and Odd (page 4) which has a review of graphing at the bottom (Resource Box).

4 Homework: Have students complete Thursday's Math Homework (Resource Box).

Friday - EQ: How do you determine if a number is odd or even?

In this lesson - 1) Review the Addition Strategy of the Week: Doubles.

2) Have students complete Weekly Assessment: Week 5 (Resource Box). This is a weekly spiral assessment.

3) Wrap up the week with any review needed. Flipchart on Doubles available.

4) Remember to complete Week 5 Graphing Activity on Scope and Sequence.

Classwork on 2.OA.3 - a. Formative Assessment (3 pages-Resource Box) - give each student only the top or bottom half of each page because the problems are duplicated on each page. Teachers need to give this to make sure that students have mastered the standard. b. Game with cards (2 pages-Resource Box) - Students will have to match up the cards. c. Color the Even Numbers Red and Odd Numbers Yellow Worksheet (2 pages Resource Box)

Summarizing Strategy: Assign Math Quiz Week Even/Odd (Resource Box).
