A cumulative assessment worksheet for the final lesson of the Operation Patterns Lab. Students must solve a complex two-step word problem by creating a tape diagram, writing a variable-based equation, and performing a reasonableness check.

A slide deck for the culminating lesson of the Operation Patterns Lab. It features a cumulative "Final Boss" problem that requires students to apply all their learned skills (rounding, tape diagrams, equations) and celebrates their completion of the intervention lab.

A student worksheet for Lesson 11 where students summarize their learning by identifying and explaining various arithmetic rules and properties they have discovered. Includes "Why" detective prompts and a pattern challenge.

A slide deck for Lesson 11 summarizing key arithmetic patterns discovered throughout the lab. Includes a Math Talk focused on explaining the logic behind odd/even sum rules and a visual summary of addition, multiplication, and square patterns.

A student worksheet for Lesson 10 where students solve complex two-step problems by first mapping out the required operations and then calculating each step. Includes a section for self-checking with an estimate.

A slide deck for Lesson 10 focusing on choosing operations in multi-step word problems. It breaks down the actions of addition, subtraction, multiplication, and division in context and models how to map out a two-step problem.

A student worksheet for Lesson 9 where students practice representing two-step word problems using equations with a letter standing for the unknown quantity. Includes multiple choice for equation matching and space for solving.

A slide deck for Lesson 9 introducing variables in two-step equations. It teaches students how to represent unknown quantities with letters and how to use parentheses to group related operations in a multi-step problem.

A student worksheet for Lesson 8 where students solve two-step word problems involving multiplication and division. It uses visual arrays and step-by-step thinking frames.

A slide deck for Lesson 8 focusing on two-step word problems involving multiplication and division. It emphasizes identifying "groups" and "items per group" as the first step in a multi-action problem.

A student worksheet for Lesson 7 where students use tape diagrams to represent and solve two-step word problems involving addition and subtraction.

A slide deck for Lesson 7 introducing two-step word problems involving addition and subtraction. It uses tape diagrams to help students visualize the relationship between parts and the whole in multi-step scenarios.

A student worksheet for Lesson 6 where students practice the "Round, Estimate, Compare" routine to check the reasonableness of their answers in addition and subtraction problems.

A slide deck for Lesson 6 focusing on the routine of checking for reasonableness. It introduces a 3-step process (Round, Estimate, Compare) to help students self-monitor their work in word problems.

A student worksheet for Lesson 5 on rounding. Students practice locating numbers on a number line between "landmark" multiples of 10 and identifying the nearest landmark using midpoints.

A slide deck for Lesson 5 on rounding. It uses a Math Talk routine focusing on number line proximity and establishes the concept of benchmark "landmark" numbers and midpoints for rounding to the nearest 10.

A student worksheet for Lesson 4 exploring the distributive property through patterns. Students practice breaking larger multiplication facts like 7s and 8s into smaller, known components like 5s and 2s.

A slide deck for Lesson 4 exploring the distributive property through patterns. Includes a split-array visual and a Math Talk routine focused on breaking large facts into known components.

A student worksheet for Lesson 3 focusing on square numbers. Students identify the visual representation of square numbers and investigate the growth pattern between consecutive squares (+3, +5, +7, etc.).

A slide deck for Lesson 3 focusing on square numbers. Includes a Math Talk and an investigation of the diagonal in the multiplication table, highlighting the growth pattern between squares.

A student worksheet focusing on skip-counting patterns of 5 and 10. Students identify units digit patterns and explain the relationship between multiples of 5 and 10.

A slide deck for investigating patterns in multiples of 2, 5, and 10. Includes a choral count routine and visual breakdowns of how these patterns overlap.

A student worksheet for the first lesson where they investigate patterns in the addition table. Includes a partial table to complete and spaces for recording observations and rules about even and odd numbers.
