# Online Games and Activities for Grades 4-5

Powerlines. Students are presented with a gameboard and several sequential numbers. They are asked to place the numbers in positions such that each line is equal to the total that is displayed on the bottom of the page. (From Oswego City School District.)

Home Run Derby Math. Students choose an operation (addition, subtraction, or multiplication), estimate the answer to a math problem presented on a baseball scoreboard, and then click "hit". The closer the estimate, the farther the baseball player hits the ball. Note that using a comma in one's answer results in a strike.

## Multiplication and Division

Speed Grid Challenge. Click on two numbers that make the equation below the grid true (e.g. __ x __ = 15 or __ x __ = 208). Students decide how many problems they want to solve in how many minutes. (From Oswego City School District.)

Home Run Derby Math. Students choose an operation (addition, subtraction, or multiplication), estimate the answer to a math problem presented on a baseball scoreboard, and then click "hit". The closer the estimate, the farther the bseball player hits the ball. Note that using a comma in one's answer results in a strike.

## Multiplication and Division Facts

The Multiplication Game. Students play against the computer or another person. When play begins, one arrow is on one of the numbers (1-9). Player 1 moves the 2nd arrow to any number (1-9). The product of those two numbers is then covered on the gameboard, in one color. Player two then moves the 1st arrow to any number, covering a new product in another color. Try to be the first to cover four numbers in a row.

Moles. Players click the mole that is holding the correct answer. Students choose one of two modes: select (click on the mole holding the correct expression) or enter (type the answer and then select the mole holding the matching expression). Students also select the level of difficulty (easy, medium or hard), changing the number of moles and the amount of time per problem. After, the game provides statistics including information about errors.

Wade’s Workout. Help Wade get in shape by punching the correct answer to a given multiplication question. (Or by choosing food for him to eat, weights for him to lift, or umbrellas along his run.) Students can work on specific facts or three sets of mixed problems. During each round, the game keeps track of the number of right/wrong answers.

Knights of Math. Players select a level (that correlates to the sets of facts it tests) and then choose the correct answers to given multiplication problems. With each correct answer, a piece of the kingdom is placed on the screen. After 60 correct answers, students can design their own kingdom.

Multiplication Grand Prix. Video-game-like practice of the multiplication combinations. A problem is posed, and the player has to click on the correct answer (of 4 choices) to get the race car to drive faster. Players can play against each other or the computer. After, the game provides statistics including information about errors.

Tug Team Tractor Multiplication. Video-game-like practice of the multiplication combinations. A problem is posed, and the player has to click on the correct answer (of 4 choices) to get the tractor to tug faster. Players can play against each other or the computer. After, the game provides statistics including information about errors.

Meteor Multiplication. A product is displayed on the spaceship and the player must shoot the correct expression (displayed on the meteors). If the player is incorrect the meteors will continue to advance towards the spaceship until they collide. After, the game provides statistics including information about errors.

Drag Race Division. Video-game-like practice of the division combinations. A problem is posed, and the player has to click on the correct answer (of 4 choices) to power the car. Players can play against each other or the computer. After, the game provides statistics including information about errors.

Demolition Division. Students are given a quotient and have to shoot down the car that displays the corresponding division expression. If students do not solve the problems fast enough, they will be shot down themselves. After, the game provides statistics including information about errors.

## All Four Operations

The Arithmetic Game. Choose numbers to complete the equation below the board. Note that some of the equations include more than one operation (eg. _ + _ ÷ _ = 9), so order of opertions is involved.

## Rational Numbers

Tug Team: Bike Fractions. In this video-game-like game, players compare two fractions and select the symbol (<, =, >) that accurately describes the comparison. Players can play against each other or the computer. After, the game provides statistics including information about errors.

Fraction Game. Students draw a fraction card and then move that amount on one or more fraction lines. The goal is to move all of the markers to the right side of the line (1).

Matching Fractions, Decimals, Percents. A concentration game played with 16, 20 or 24 fraction, decimal, and percent cards. Students find pairs of cards that are equivalent. (From NRICH.)

## Patterns, Functions, and Change

Mental Maths. Drag a number into the machine, see what happens to it, and use that information to guess the rule. Students guess the rule by entering the operation and the number (e.g. ÷ 3 would mean the machine divides every number that goes through it by 3). Students can experiment as long as they like before making a guess.

Function Machine. Students have to guess the rule the machine is using to change numbers as they pass through it. The machine collects data about the numbers that have gone into and out of the machine. They guess the rule by entering the operation and the number (e.g. x 10 would mean the machine multiples every number that goes through it by 10). (From PBS's Cyberchase Games.)

## Geometry and Measurement

Billy Bug. Students try to move a bug to a given point on a coordinate grid. Students are timed to see how long it takes them to find 10 coordinates. (From Oswego City School District.)

Point of View. Students select the different characters and create the point of view for each individual character until all four have been figured out. If students are having difficulty they can receive hints to help them determine the answer. (From PBS's Cyberchase Games.)

Banana Hunt. Students are given a degree measurement and have to estimate where to move the monkey so that it is as close to the measurement as possible. The closer they are, the more bananas they are given as a reward. (From Oswego City School District.)

Sal’s Sub Shop. Students use a ruler to cut a sub roll to a specific measurement; then make the sub. (Note: You can turn the sound off.)
