A focused review lesson on key math skills including place value, skip counting, number forms, and multi-digit addition and subtraction. Features a gradual release model (I Do, We Do, You Do) with integrated place value supports.

A series of five daily warm-up questions focused on converting number names into standard form, progressing in difficulty from 3-digit numbers to the thousands.

A lesson focused on identifying the mathematical operation needed to solve word problems by analyzing the actions and relationships described in the text. Students learn to 'decode' story problems into number sentences across all four operations.

An assessment and data tracking bundle designed to evaluate a student's ability to identify mathematical relationships (joining, separating, and equal groups) within word problems and translate them into number sentences.

A lesson focused on subtracting 1-digit numbers from multiples of ten (20, 30, 40, etc.) using counting back and regrouping strategies. Includes a visual slide deck and a themed practice worksheet.

An introductory lesson for first graders on partitioning circles and rectangles into two and four equal shares, using the language of halves and fourths.

A focused assessment on skip counting by 2s within the range of 2-10. Students identify the missing number in a single sequence to demonstrate mastery of the pattern.
