A series of math quests where students practice addition and subtraction within 20. Through medieval-themed challenges, students build fluency using ten-frames and number lines.

A series of medieval-themed math challenges focusing on addition and subtraction fluency within 20. Students use visual models like ten-frames and number lines to solve operational problems.

A precision-focused drafting-themed review of 4th grade Measurement and Data (MD) standards. Covers units and conversions (MD.1), measurement word problems (MD.2), area and perimeter (MD.3), line plots (MD.4), and angle measurement and addition (MD.6-7). Division has been removed from the curriculum.

A comprehensive slide deck covering measurement in inches (halves and fourths) and interpreting data on line plots, provided in both English and Japanese.

A cumulative review of all standards covered in the 10-day intensive program.

Strategies for solving two-step word problems involving addition, subtraction, and multiplication with unknowns.

Covers finding the perimeter of polygons, including finding unknown side lengths.

Uses partitioning of rectangles to illustrate the distributive property and additive nature of area.

Introduces area through tiling and relates it to multiplication of side lengths.

Focuses on comparing fractions with the same numerator by reasoning about the size of the denominator.

Teaches comparing fractions with the same denominator using area and length models.

Focuses on thirds and sixths using length models (number lines) to find equivalent fractions.
