"A math game intended for upper elementary and middle school students that helps students enjoy practicing their order of operations. The game encourages students to use higher order thinking to solve the "target" number by working backwards given the answer but not the equation."
"10 Frame Fill" provides children practice with recognizing additive "10 Families" (e.g., 1 and 9, 2 and 8, etc.). Set the 10 Frame to fill in sequence or randomly. Use contrasting color chips to fill the 10 frame as you determine the answer. Select to show a corresponding number sentence.
"Explore math with the fast and powerful Desmos Graphing Calculator. Plot any equation, from lines and parabolas to derivatives and Fourier series. Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more—all for free."
"Move beyond arithmetic with the Desmos scientific calculator! In addition to the basic operations, take advantage of a variety of built-in functions for exploring trigonometry, statistics, combinatorics, and more. Or, define and evaluate your own functions -- all for free."
"Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around the pegs to form line segments and polygons and make discoveries about perimeter, area, angles, congruence, fractions, and more."
"Graph 3D functions, plot surfaces and do 3D geometry with our free 3D Grapher. Easily solve 3D math problems, graph 3D functions and surfaces, create geometric constructions in 3D, save and share your results. With Augmented Reality enabled, you can place math objects on any surface and walk around them!"
"Explore functions, solve equations, construct geometric shapes and 3D objects. Graph functions, roots, and extrema. Find derivatives and integrals. Create tables of values. Solve equations and 3D math problems. Construct and analyze polygons, circles and conics. Create dynamic geometric constructions in 2D. Use Augmented Reality to explore 3D math objects in real life."
"Math Clock helps students become fluent working with time. Learners use analog clocks with geared or free-moving hands to learn how to tell time, explore jumps with count by numbers, and visualize story problems involving intervals of time."
"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."
"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."
"Number Line helps students visualize number sequences and demonstrate strategies for counting, comparing, adding, subtracting, multiplying, and dividing. Choose number lines labelled with whole numbers, fractions, decimals, or negative numbers. Or use a blank number line, with or without tick marks."
"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 Rack facilitates the natural development of children’s number sense. The movable, 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."
