Pearson Education 1 1 Activity 2 Activity 3 Discussion 4 Session Follow-Up A C T I V I T Y Introducing Plus or Minus 1 BINGO 15 Min cl ass Gather students to introduce Plus or Minus 1 BINGO. You will need a set of Primary Number Cards without the zeros or the Wild Cards, counters, and a Plus or Minus 1 BINGO Gameboard (Student Activity Book page 10A or C2). Explain that two students share one gameboard. Ask a volunteer to be your partner and play a sample game. We re going to learn a new game called Plus or Minus 1 BINGO. The object is to work together with a partner to try to cover one whole row on the gameboard. You can cover a row horizontally, vertically, or diagonally. [Use gestures to illustrate.] To play, you turn over the top card in the deck. Then, you can add 1 to that number. Or, you can subtract 1 from that number. Together, you and your partner agree on which problem to solve, and then cover the answer on the gameboard. Let s try it. Ask your volunteer to turn over the top card. [Toshi] turned over a 5. So we can do 5 plus 1 or 5 minus 1. We can put a counter on the number that is one more than 5, or we can put a counter on the number that is one less than 5. What number would we cover if we did 5 plus 1? What if we did 5 minus 1? Ask students to determine the answers to 5 + 1 and 5 1, and have them share their strategies for doing so. Have cubes available to model and solve the problems as needed. Use addition and subtraction notation to record the two equations (5 + 1 = 6 and 5 1 = 4) on the board. Choose 6 or 4, and use a counter to cover that number on the gameboard. Play a few more rounds, until students understand the object of the game and how to play. Be sure to include a sample round where the card turned over is 1, so that you can discuss 1 1. Explain that there may be a turn when a number players choose to cover is unavailable (e.g., a player may want to add 4 + 1, but all the 5s are covered). In this case, they should try the other possibility (e.g., 4 1). If both answers are unavailable, they should take another card. Name 51,T How Unit Many Title of Each?

More Ways to Play Players use different colors and try to cover a whole row. Play with the Wild Cards. A Wild Card can be any number. Play to fill more than one row or the whole board.

Players turn over a Primary Number Card and decide whether to cover 1 more or 1 less than that number on their gameboard. They try to cover one row of the gameboard vertically, horizontally, or diagonally. Provide copies of Plus or Minus 1 BINGO (C3) as needed. Ongoing Assessment: Observing Students at Work Students add 1 to, and subtract 1 from, numbers up to 10. As you observe, occasionally ask students about addition problems posed in the reverse (e.g., 1 + 5 instead of 5 + 1). Use Assessment Checklist: Add and Subtract 1 (C4) to keep track of your observations of students fluency with these facts. 1 How fluently do students add 1 to numbers to 10? Do they just know the sum? Count 1 more? Need to model the problem? Are students as fluent adding a number to 1 (e.g., 1 5) as they are with adding 1 to any number (e.g., 5 1)? How fluently do students subtract 1 from numbers to 10? Do they just know the difference? Count back 1 from the given number? Need to model the problem? How do students decide whether to add or subtract 1? Are they playing strategically? Differ entiation: Supporting the R ange of Learners Assessment Checklist: Add and Subtract 1 Adds 1 to Adds any Subtracts 1 from Notes any number number to 1 any number Student (e.g., 5 1) (e.g., 1 5) (e.g., 5 1) R esource Masters, C4 C4 Pearson Education, Inc., or its affiliates. All Rights Reserved. 1 If this game seems difficult for some students, play in a small group with them. Make sure that they understand that each card picked results in two problems. Some students will need to be challenged to consider both operations, rather than adding each time. Others may benefit from further work connecting counting forward (and backward) with the idea of adding (and subtracting) 1. Use the context of staircases (from Session 2.4) to clarify the concept of one more and one less. Begin a chart for words like add, plus, subtract, and minus, and have students help you record examples and illustrations. Pairs can work together to cover the whole gameboard. Or, they can work individually to cover an entire row, each in their own color counters. CC6 Investigation 2 Counting and Comparing

Discuss students strategies for adding or subtracting 1 to numbers up to 10 by playing several rounds of Plus or Minus 1 BINGO against the class. Involve many students by having one turn over and name the number; one record the addition problem; and another record the subtraction problem. Discuss and model students strategies for solving the problems. Students might say: I found the number on the number line. Plus 1 is one more number and minus 1 is the number before it. 5. 8 1 = 6. 3 1 = 7. 5 1 = 8. 7 1 = Session 2.5A Unit 1 Student Activity Book, Unit 1, p. 10B; Resource Masters, C5 10B I would show the number with my fingers. Then I would put up one more finger, or put one finger down. I used cubes. I d take that many, then add one more or take one away. I did it in my head. If you add 1, it s like saying the next number when you count. If you minus 1 it s like counting backwards. Also discuss how students are deciding which problem to solve or which number to cover on their gameboards.
