The Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around pegs to form line segments and polygons and make discoveries about perimeter, area, angles, congruence, fractions, and more.

Practice mental multiplying and estimation with Motion Math: Wings! This fun math game helps children ages 4 and up develop a conceptual understanding using six different visual forms. It's simple to play – you just tilt your bird to the bigger number.

MathTappers: Equivalents challenges players to find groups of tiles (pairs or triples)
showing equivalent fractions, decimals and/or percents. To assist the player, the game
can display a numberline, a 100-grid or a pie chart showing the value of the initial
fraction selected.

MathTappers: Fraction Estimation is designed to help learners to build their intuitive understanding of fractions by helping them to relate fractions (both symbols and pictures) to the nearest half (e.g., 0, ½ 1, 1½, 2, etc.) and then to extend their understanding by challenging them to use fraction estimates in addition and subtraction problems.

MathTappers: Clockmaster is a game to help children make the connection between hours and minutes and to help them become fluent in both reading and setting time on digital and analog clocks.

While flashcards have some utility in helping people memorize, they are best used after
we have mastered a topic and need to build fluency – they are not magic and won’t
support the development of understanding on their own. MathTappers: Multiples is a
simple game designed first to help learners to make sense of multiplication and division
with whole numbers, and then to support them in developing fluency while maintaining
accuracy.

MathTappers: Find Sums is a simple game designed to help learners to make sense of addition (and subtraction as a related operation), and then to support them in developing accuracy and improving their speed.

MathTappers: Numberline is a learning game that challenges players to find the locations of numbers on a numberline. This game allows players to develop their understanding of our number system and their proportional reasoning skills by giving them an opportunity to consider the relative positions of whole, integer and real numbers on a numberline.
