Help your students remember different division strategies and methods (with 1-digit divisors) with this bookmark/handout! Included are: base-10 groups, estimation using compatible numbers, area models, partial quotients, and standard algorithm. Thinking flexibly about numbers and realizing that the standard algorithm is NOT always the most efficient method is such an important concept for younger students. Sometimes, it can be overwhelming for students to remember all of the different options to

Help your students remember different multi-digit multiplication strategies and methods with this bookmark/handout! Included are: base-10 arrays, distributive property, area models, compensation, partial products, and standard algorithm. Thinking flexibly about numbers and realizing that the standard algorithm is NOT always the most efficient method is such an important concept for younger students. Sometimes, it can be overwhelming for students to remember all of the different options to see wh

Help your students remember different addition and subtraction mental math strategies with this bookmark/handout! Thinking flexibly about numbers and realizing that the standard algorithm is NOT always the most efficient method is such an important concept for younger students. Sometimes, it can be overwhelming for students to remember all of the different options to see which works best for them in different circumstances. This color-coded bookmark aims to support them in their math work. Each
