Money Board

A work mat stocked with real pennies, nickels, dimes, quarters and one, five, ten and twenty dollar bills. Click money out of the bank to build an amount, then tap the pieces one at a time to count on — a running total appears under each one (10¢, 20¢, 21¢…). Click Show the Amount to reveal the total, the words, and a coin-by-coin breakdown, or set an amount to build and let the board check it.

Hundreds Chart Explorer

A big interactive hundreds chart for numbers to 1,000. Six activities — Explore, Count, Patterns, Mystery Number, Add & Subtract, and Challenge Me — ask students to predict before the chart shows the answer, then animate the jump and write the equation (293 + 10 = 303). Charts switch automatically when a jump crosses into the next hundred. A Teacher Settings panel controls the number range, activities, difficulty level, counting increments, hidden numbers, and questions per session. Teacher Mode turns the same chart into an open whiteboard manipulative for whole-group lessons — multi-colour highlighting, hide and reveal, row and column shading, a pattern tool that reveals one number at a time, a jump tool that writes the equation as you go, a “Where will we land?” pause, 3×3 to 5×5 partial charts, and a Teaching Focus menu that trims the toolbar to just what the lesson needs. A built-in How To guide walks through every feature and can be printed.
