Investigates student recognition of shape attributes, partitioning rectangles into grids, and counting vertices prior to 3rd-grade geometry and area.

Evaluates prerequisite skills for time, measurement, and bar/picture graphs to ensure readiness for complex measurement topics.

Assesses understanding of equal shares, partitioning shapes into halves, thirds, and fourths, and naming fraction parts prior to 3rd-grade fraction units.

Diagnoses readiness for 3rd-grade place value, multi-digit addition, subtraction, and estimation, based on 2nd-grade standards.

Focuses on prerequisite skills for multiplication and division, including equal groups, skip counting, arrays, and repeated addition.

A diagnostic pretest and intervention package designed to assess and remediate 2nd-grade prerequisite math skills (equal groups, repeated addition, and basic arrays) before starting 3rd-grade Unit 1 Multiplication and Division. Includes a student quiz, targeted intervention worksheets, and a comprehensive teacher guide with rubrics and answer keys.

A math assessment lesson focusing on 3-digit by 2-digit multiplication and basic division with rich visual scaffolds (grid alignments, base-ten block representations, equal sharing groups, and arrays) designed to support students who struggle with abstract math concepts.

A structured progress monitoring kit for division and multiplication, designed with retro-game aesthetics. Includes two highly-scaffolded visual probes, an interactive student tracker, and a comprehensive teacher guide with IEP goals.

A hands-on, community-based learning activity where students visit a supermarket to locate prices, compare deals, and practice budget management in a real-world setting.

A lesson introducing subtraction without borrowing using color-coded grids and place value alignment. Students practice aligning digits in tens and ones columns before expanding to hundreds.

A scaffolded math lesson focusing on long division with remainders using grid paper alignments to keep place values perfectly structured.

A highly visual, structured lesson teaching the standard U.S. addition algorithm within 1,000 with regrouping. It features color-coded grid worksheets, place-value scaffolding, and step-by-step slides designed with dedicated carryover/regrouping boxes for student support.

A cross-curricular math and science lesson for grades 3-5. Students explore fractions as parts of a whole by partitioning the geometric, silica-shelled structures of microscopic diatoms.

An assessment and supporting resources for students who struggle with multi-step word problems. It features simplified language, rebus-style icon clues, and a step-by-step graphic organizer workspace embedded in every problem.

A scaffolded math toolkit designed to help students break down multi-step word problems using visual graphic organizers, reading accommodations, and a detailed teacher error-tracking framework.

A mental math lesson introducing the compensation strategy for addition within 20 using a playful candy shop theme. Students shift amounts between addends to create 'friendly tens' (e.g., 9 + 5 becomes 10 + 4), practicing this mentally during a slide-guided warm-up and on paper with a themed student worksheet.
