Properties of Operations

Big Ideas

Mathematical relationships among numbers can be represented, compared, and communicated.

Mathematical relationships can be represented as expressions, equations and inequalities in mathematical situations.

Patterns exhibit relationships that can be extended, described, and generalized.

Essential Questions

How can mathematics support effective communication?

How are relationships represented mathematically?

How can expressions, equations and inequalities be used to quantify, solve, model, and/or analyze mathematical situations?

MATH GAMES TO MAKE PRACTICE FUN

  1. Math Tic Tac Toe- played like the traditional game but inside each square is a math problem to solve before the player can put an X or O in the space.
  2. Puddle Jump-This is a fun review game to get kids up and moving that can be played with just one child, or a small group. The students select a puddle to stand on to start. With young children, you can simply call out numbers to practice number recognition. They then jump to the correct number. Or to work on counting and sequencing, have kids start at the beginning and count and jump in order. You could also use this to practice skip counting and multiplication facts. Or use a variety of numbers and practice addition and subtraction skills. If you’re working with older kids, you may want to have them start at their desk (or lined up on the wall) with a whiteboard to solve the problem. Then when you call out a math problem, they solve it on their board and race to the correct puddle. The kid who solves it and makes it to the correct puddle first wins that round.To practice with fractions, write a variety of fraction on your “puddles.” Then let students put them in order and jump across the puddles stating the fraction values. Then call out problems related to fractions for them to jump to.
  3. Spiral: Simple Card Game- To start, the first player rolls a die and moves that number of cards on the game board. They must then add/subtract/multiply or divide the number on their die with the value of the card they landed on. If they solve it correctly, they stay there, otherwise they go back to their previous position. the first player to land exactly on the last card and correctly solve the problem wins!
  4. Math Bingo- Played like traditional bingo. You can have the students set up their game boards by writing numbers of their choice in the space. You will be calling out problems based on what facts you are reviewing and they have to solve the problem. Then cover the square on their board that has the correct answer if they have it.
  5. Target Math Card Game- deal each player 4 cards. (Or more if you’d like to try different variations) Place the remainder of the deck face down in the center and flip over the top card. This is the “target” value. Players then try to reach the “target” using their 4 cards and any operations you’d like to practice (addition, subtraction multiplication, division, etc.).

Doubles Plus One game

Partners take turns flipping over a card in the deck and explaining how they could use the doubles plus one strategy to find the sum. Play continues until one play has all their numbers covered on the board.
