Equation Builders

A multi-phase diagnostic, progress monitoring, and mastery assessment sequence for fraction division. Targets conceptual visual models, procedural inversion strategies, and mixed number operations.

A 40-minute introductory lesson on the 2-digit US standard addition algorithm with regrouping to the tens place, connecting base-ten manipulatives on place value mats directly to carrying digits.

A printable 2-up half-sheet exit ticket featuring primary headline/midline/baseline name and date lines, where students input numbers into standard algorithm charts and solve two quick check problems.

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 high-engagement 15-minute small-group math lesson targeting TEKS 1.3.B, using concrete manipulatives and pictorial models to solve joining and separating word problems within 20 with unknowns in various positions.

Teacher answer key for the 12-problem Tens Trade Worksheet, displaying fully completed place value algorithm charts with highlighted carried tens and step-by-step solutions.

A comprehensive two-day mathematics sequence for early elementary students focusing on comparing two-digit numbers. Day 1 emphasizes concrete, hands-on place value modeling with base-ten manipulatives and cut-out symbols, while Day 2 cements conceptual mastery through visual representations, structured paper-based practice, and reasoning tasks.

A focused lesson on solving multi-step linear equations in one variable with the distributive property, constant terms, and variables on both sides in accordance with TEKS A.5(A).

A two-page student worksheet featuring primary headline/midline/baseline name and date lines with 12 independent practice problems where students input digits into standard algorithm place value charts and solve with regrouping.

A hands-on Kindergarten mathematics sequence covering one-to-one counting, cardinality, numeral handwriting 1 to 10, and representing quantities with concrete circle sets and ten-frames.

A hands-on early elementary math lesson focused on decomposing quantities within 5 using pictured sets, concrete manipulatives, and addition sentences. Students explore part-whole relationships, record multiple combinations for the same total, and articulate their mathematical reasoning.

Visual instructional slides guiding students through the 10-ones-for-1-ten trade, the teacher model of 37 + 25, partner guided practice of 48 + 26, and the standard algorithm carrying box.
