A collaborative data collection and graphing project where students partner up to survey 5th graders, collect tally mark data, and design a custom poster featuring a line plot and an alternative graph style.
A high-engagement, adventure-themed 4th-grade math spiral review game. Students solve word problems spanning fractions, multi-digit operations, area, and decimals to complete a fantasy quest, perfect for online display or in-person play.
A math lesson on division using the partial quotients (Big 7) method. Students explore division word problems and extra practice using a 'friendly numbers' multiplication helper and subtraction workspace in a sci-fi space cargo theme.
An immersive, pirate-themed math escape room where students solve puzzles in multi-digit multiplication, long division, fraction operations, and decimals to crack codes and discover Captain Blackbeard's legendary lost treasure.
A comprehensive practice and support system designed to reinforce fundamental operations, including fractions, multi-digit integers, and decimals. Features a structured 2-page workspace worksheet, a detailed step-by-step teacher answer key, and a visual diagnostic anchor chart.
An introductory lesson on breaking down two-step word problems involving multiplication and division using clear, visual bar diagrams.
A math lesson focused on solving real-world division problems using friendly numbers (like 5 and 10). It includes warm-up slides and a spacious multi-page worksheet.
A 2-step word problem math lesson designed for 3rd to 5th grade students using mixed operations and 2-3 digit numbers. Includes custom graphic organizers for Step 1 and Step 2 of each word problem to guide and scaffold student problem-solving, plus an answer key.
Covers Day 7 (Advanced Mixed Number Regrouping) and Day 8 (Multi-step Real World Word Problems). Students master multi-step tasks, abstracting their visual models into numerical strategies.
Covers Day 5 (Mixed Numbers with No Regrouping) and Day 6 (Introduction to Regrouping with Mixed Numbers). Students transition from simple subtraction of mixed numbers to decomposing a whole to subtract a larger fractional part.
Covers Day 3 (Subtracting from a Whole Number) and Day 4 (Solving Word Problems with no regrouping). Students decompose whole numbers into equivalent fractions to solve subtraction equations and decode realistic scenarios.
Covers Day 1 (Area Models) and Day 2 (Number Lines) of subtraction with like denominators and no regrouping. Students build foundational conceptual understanding of subtraction as 'taking away' and 'distance between' using highly visual, collaborative thin-slicing tasks.
