All apps are available in two or more versions: a web app which works on all modern browsers, and downloadable versions for specific operating systems and devices, such as Apple iOS for iPad. These apps are based on the visual models featured in Bridges in Mathematics K-5.
Fractions lets students use a bar or circle to represent, compare, and perform operations with fractions with denominators from 1 to 100.
Geoboard is a tool for exploring a variety of mathematical topics introduced in grades K-8. Learners stretch bands around pegs to form line segments and polygons and make discoveries about perimeter, area, angles, fractions, and more.
Math Vocabulary Cards help students deepen their conceptual understanding of key terms in mathematics. Each card features three sections: a math term, a representative example or model, and a concise definition.
Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range.
Number Line helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students use the pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide.
Number Pieces helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students use the number pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide.
Number Pieces Basic is a simplified version of the Number Pieces app, designed for use with primary students. It has fewer features, putting greater focus on place value, counting, addition, and subtraction. Note that Web version is full Number Pieces app.
Number Rack facilitates the natural development of children’s number sense. Rows of moveable, colored beads encourage learners to think in groups of fives and tens, helping them to explore and discover a variety of addition and subtraction strategies.
Students use Pattern Shapes to explore geometry and fractions, creating their own designs, or filling in outlines. As they work with the shapes students think about angles, investigate symmetry, and compose and decompose larger shapes.
Money Pieces help students visualize and understand money values and relationships. Two versions of coins and bills are provided: virtual currency pieces that replicate the appearance and relative size of U.S. coins and the dollar bill, and area money pieces.
