Polygon Builders Checklist

A three-day gradual progression sequence introducing young learners to basic multiplication word problems using familiar, repeated groups of two. Students progress from visual pair models to student-drawn representations and independent story problem solving.

A third-grade math lesson introducing the distributive property of multiplication by breaking tricky two-digit numbers apart into a friendly ten and leftover ones.

A three-part teacher guide containing concise, classroom-ready mini-lesson outlines for Grade 2 math fact strategies: High Doubles (beyond 5+5), Near Doubles (Doubles ±1), and Pretend a Ten / Make 10. Each lesson provides explicit modeling scripts, visual mental models, guided math talk prompts, active partner practice routines, and common misconception watch-outs.

A targeted two-week second grade intervention unit designed to build fluency in adding and subtracting within 100. Emphasizes place value decomposition, properties of operations, and the relationship between addition and subtraction.

A targeted Grade 3 Unit 3 math review lesson covering distributive and associative properties of multiplication, multiplying by multiples of 10, arithmetic patterns, and equal-group division. Students review core strategies through guided slide models and apply skills on an assessment-aligned practice packet.

A complete 2-page teacher answer key for the Break Apart Ten Worksheet. Contains fully worked-out step-by-step solutions for every problem, highlighted correct values, and teacher notes on common student misconceptions.

A rigorous 2-day mini-unit for Grade 3 mathematics adapted from Uncommon Schools inquiry curriculum, focusing on arithmetic patterns and operational rules. Day 1 explores increasing patterns through addition and multiplication, while Day 2 targets decreasing patterns through subtraction and division.

An engaging Thanksgiving math and creative design lesson where students explore counting, data analysis, and procedural writing inspired by an illustrated dancing turkey cupcake with colorful sprinkles.

A 2-page print-ready student worksheet for third graders practicing the distributive property of multiplication by breaking teen numbers apart into a ten and leftover ones. Features a reference anchor, warm-up number splits, guided step-by-step problems, independent practice, and a real-world word problem.

A collection of rigorous, standards-aligned elementary instructional units spanning literature analysis and foundational mathematics mastery.

A comprehensive 3rd grade progress monitoring system featuring five standardized 5-problem benchmark probes for addition and subtraction word problems within 100 (with and without regrouping), alongside an educator tracking guide and answer keys.

An 8-slide instructional presentation for third graders explaining the distributive property of multiplication by breaking numbers apart using a 10. The guided practice is split across two slides—first presenting the problem with thinking prompts, followed by a dedicated slide showing the full steps and solution.
