Investigate Math: Grade 4 Open-Ended Math Problems to Develop Flexible Thinking Skills

Designed to give students opportunities to investigate math concepts and skills more deeply, the activities in this book are open-ended and can be used repeatedly. Through the use of manipulatives, representational drawing, and writing, students look at math ideas from various angles and explore how new concepts fit into what they already know. Skills include multiplication, division, operations with multi-digit numbers, fractions, decimals, area, perimeter, angles, and more.
