Level 1

Build & reason — hands-on number surfaces

Three ways to feel how numbers work, rebuilt for the browser — the same ideas as the iOS app.

Number Studio Build a number from thousands, hundreds, tens, and ones — watch the standard, expanded, and word forms update, and trade 10-for-1 to regroup. Number Line Place a number, round to the nearest ten or hundred, work with integers and absolute value — and solve by choosing your own jumps. Rekenrek A quick-look bead rack: see a quantity in fives and tens (don’t count!), and build make-ten pairs.

Practice the concepts
