Measure Mission

A comprehensive multi-day division unit introducing students to the partial quotients method with one-digit divisors. The sequence moves from conceptual area models and friendly multiplication chunks to the standard Big Seven algorithm, remainder problem solving, and error analysis.

A comprehensive 3rd-5th grade mathematics lesson using Schema-Based Instruction (SBI) to empower students to analyze, diagram, and solve multi-step word problems through visual structural models.

An engaging 2-page print-ready classroom math game featuring a mystery investigation game board, 12 multi-step case challenge cards, and detective evidence trackers for 2-4 players.

Séquence complète d'apprentissage des mathématiques pour le cours moyen (CM1/CM2) axée sur la maîtrise experte de l'addition des nombres entiers. Les élèves incarnent les ingénieurs et navigateurs de la base spatiale Artemis et mobilisent le calcul en ligne, l'estimation d'ordre de grandeur, l'algorithme posé et la résolution de problèmes additifs.

A comprehensive grades 3-5 mathematics lesson where students act as detective sleuths to categorize multi-step word problems into four core cognitive schemas before computing. Students map situations using Combine, Compare, Change, and Equal Groups models to overcome cognitive overload and solve multi-step problems with accuracy.

A 2-page printable board game for grades 3-5 students to practice diagnosing math word problem schemas. Includes a full 20-space Crime Scene Map game board, printable detective player pawns, 16 multi-step case clue cards across all four schemas, badge tokens, and a self-verifying answer decoder.

Une séquence complète de 5 séances pour cours double CM1-CM2 sur l'addition des nombres entiers, conforme aux programmes du BO n° 16 d'avril 2025. Elle articule calcul mental automatisé, stratégies de calcul réfléchi, technique opératoire des grands nombres, modélisation en barres et évaluation critériée.

A focused data interpretation lesson where students analyze sports statistics presented in a bar graph. Students practice calculating totals across categories, identifying minimum and maximum frequencies, and solving range problems using 'at least' and 'at most' conditions.

A 2-page printable student detective casebook worksheet for practicing Schema-Based Instruction with multi-step math word problems. Features an explicit schema reference key, guided multi-step case files with designated blueprint drawing areas, computation workspaces, and self-check reflection prompts.

A three-day intervention sequence focusing on 3-digit subtraction with standard algorithm regrouping. Tailored for resource math groups with place-value alignment grids and reduced visual load across single borrowing, double borrowing, and borrowing across zeroes.

A targeted 3rd-5th grade math lesson using explicit schema-based instruction (SBI) to decode multi-step word problems. Students classify problem structures into Total, Difference, and Change schemas using visual blueprint models before computing solutions.

A 2-page print-ready student investigation worksheet where learners classify multi-step word problems into graphic schema organizers (Total, Difference, Change, Equal Groups) before solving.
