Number sense and mental math are such crucial skills to build in the early years. Working with and manipulating numbers without paper builds students' understanding of the numbers, and their ability to work through math problems quickly and successfully later. These Number Puzzlers present students with a number to make using addition and/or subtraction given another set of numbers. Each number has multiple possible combinations, building mathematical discourse in your classroom as students explain how they came to their solution and expand on their peer's understanding. A set of answers is included to help you see potential combinations and guide your students through new ways of using the numbers. Most solutions have combinations that include using addition and subtraction, helping strengthen students understanding of the operations.
Help build your students mental math skills and number sense in just a few minutes each day.
