Order of Operations, One Step at a Time: Order Up!
Order Up! is a no-prep, self-checking digital tool for grades 5–6: students pick the next step of an expression, solve it, and watch it collapse, with color-coded rules, hints for the common mistakes, brackets, exponents and word problems.
Plotting Points in Four Quadrants: Coordinate Plane Explorer
Coordinate Plane Explorer is a no-prep, self-checking digital tool for grades 5–6: plot and name points in all four quadrants, reflect across the axes, find distances and rectangle area, and solve treasure-map word problems and mystery pictures.
Adding and Subtracting Fractions with Fraction Bars: Add & Subtract Fractions
Add & Subtract Fractions is a no-prep digital tool for grades 4–6: fraction bars on the same size whole, cut into the same size parts, then put together or taken away, with mixed numbers, regrouping and simplest form.
Multiplying and Dividing Fractions with Area Models and Fraction Bars: Multiply & Divide Fractions
Multiply & Divide Fractions is a no-prep digital tool for grades 5–6: area models for a fraction of a fraction, fraction bars for fraction × whole, and fraction pieces laid along a bar to divide, with every answer in simplest form.
Solving Equations with Integers on a Balance Scale: Algebra Balance with Integers
Algebra Balance with Integers is a no-prep digital tool for solving equations with negative numbers: bags, tiles and red −1 balloons on a balance scale, zero pairs, and negative answers, from x + 7 = 3 to x on both sides and story problems.
Adding and Subtracting Decimals with Base-Ten Blocks: Add & Subtract Decimals
Add & Subtract Decimals is a no-prep digital tool for grades 4 to 6: students loop 10 tenths to SNAP them into a whole, or break a whole with a hammer, so regrouping with decimals makes sense. Tenths, hundredths, thousandths and mixed.
Algebra Balance : Solving Building Writing Equations with a Balance Scale
Algebra Balance is a no-prep digital tool for solving equations: mystery bags, 1 tiles and −1 balloons sit on a balance scale, and students take away, add, divide or multiply both sides until one bag is alone, from x + 4 = 9 and x − 4 = 5 to x on both sides and story problems.
Decimal Place Value with Base-Ten Blocks and Number Lines: Build a Decimal
Build a Decimal is a no-prep digital tool for decimal place value: students build tenths, hundredths and thousandths with base-ten blocks, with wholes and parts kept apart, and see each number in words, as a fraction, in expanded form and on a number line.
