A high-tech exploration of Soroban abacus mechanics, framed as calibrating a powerful logic engine through complement techniques and precise multiplication chains.

This lesson focuses on mastering three-digit subtraction with regrouping using color-coded visual supports and step-by-step procedural breakdowns. Designed with Special Education accommodations in mind, students will learn to navigate place value shifts from ones to tens and tens to hundreds.

Teaches students to identify fractions within a group of discrete objects (sets), rather than a single continuous whole.

Explores fractions that represent more than one whole, using visual models and decomposition to understand values like 6/4 and 8/6.

Focuses on identifying parts of a whole, understanding numerators and denominators, and modeling fractions by dividing shapes into equal parts.

A high-energy lesson focused on mastering double-digit addition and subtraction with regrouping through a 'Tactical Mission' theme. Students practice vertical alignment and precision in their calculations.

A comprehensive lesson on 3-digit subtraction with a single regrouping (borrowing) step, using visual models and structured practice.

A fun, bakery-themed lesson focusing on solving double-digit addition word problems. Students will learn to identify key information in stories and use addition strategies to find the total number of tasty treats.
