Match shapes and numbers to earn stars in this fractions game. Challenge yourself on any level you like. Try to collect lots of stars! The main topics of this interactive simulation include fractions, equivalent fractions, and mixed numbers.

Looking for a fun way to learn about fractions? Playing this fraction game will help you to learn all about them. To play the game, you simply click on the target type of fraction while avoiding the others. The game includes three rounds and each round has a different target. The targets include: mixed numbers, fractions that are greater than or equal to one, and fractions that are less than one-half. Your goal is to complete each round in the shortest amount of time possible.

Explore fractions while you help yourself to 1/3 of a chocolate cake and wash it down with 1/2 a glass of orange juice! Create your own fractions using fun interactive objects. Match shapes and numbers to earn stars in the fractions games. Challenge yourself on any level you like. Try to collect lots of stars!

Students must think about the factors of each number as they play this game. Students quickly learn the value of selecting prime numbers as a strategy. The beauty of the game design is that students will review the factors of many numbers and mentally add the sum of these factors together in search of the "best move."

Gingerbread men and gingerbread houses enjoy special popularity around the holidays, but many of these gingerbread activities are timeless and complement literature titles that teachers use at the beginning of school or after the holidays. It's very easy to incorporate mathematics into a study of gingerbread men, and students will enjoy the data collection activities and games while learning math skills and deepening their understanding of important mathematical concepts. Look through these math activities and add some to your repertoire. Consider broadening the gingerbread math to include measurement, games and problem solving this year.

Student-facing 7th grade math resources. Covers scale drawings, proportion, percentages, probability, expressions, and geometry.

This site features a video overview of Addition (Sums to Twenty) for 1st Graders.

Students learn the patterns in the hundred board by assembling puzzles. Teachers are able to assess student use of patterns in rows and columns by observing the student at work. This task is easily differentiated to accommodate the varied levels in a first grade class by changing the number of pieces and the shape of the pieces. Puzzle bags should be sequentially lettered so that students progress through harder versions of the task. Finally, students are asked to create their own puzzles for classmates to solve.

This course features a video review and an interactive assessment activity for selecting the correct addition sequence. It is aimed at first graders.

These strategies support active student participation in math lessons and allow teachers to assess the developing proficiency levels of all students in the class by walking around to monitor student responses. These strategies are especially effective during the Mental Math part of an Everyday Mathematics lesson.

Dominoes have become a staple in most primary classrooms. They build upon dice patterns and are often used to model decomposition of numbers, building student knowledge of addition facts. They are an excellent manipulative for primary students to use and these are some examples of how students might use dominoes in the math center. Try these domino games with students to improve math skills and number recognition. Encourage students to play these games at home with their families, using real dominoes or paper copies.

These activities were designed to introduce or reinforce important math concepts and skills using seasonal themes. The games capitalize on students' fascination with spiders at Halloween time.

Bats are a common theme at Halloween. Use these resources to capitalize on student interest in bats and develop student understanding of common mathematical patterns.

Students need many concrete experiences with fractions to develop a deep understanding of the three models of fractions: area, linear and set models. Teachers need to address all three models in well-designed instructional activities so that students develop a rich concept of fractions that they can use to make sense of numbers, operations, measurement and probability. The Math Tours include: activities, problem solving, games, writing to learn, templates, math-literature connections, and web links. Each page has a left navigation bar to easily take you through the tour and back to the homepage or the math topics page.
