Multiplying Fractions by a Whole Number Anchor Chart

Created by

This anchor shows students step by step how to turn a whole number into a fraction and solve using standard algorithm. It also shows them how to model multiplication of a fraction and a whole number on a number line, with an area model, and with repeated addition.

Area Multiplication: Teaching Multiplication with Understanding

Created by

Teacher to Teacher Press

This activity shows students what multiplication is and why it works. It is a great alternative to the more common multiplication algorithm and addresses Common Core Standard 4.5 in Numbers and Operations in Base Ten. Area multiplication leads into the my extended activity, Mental Multiplication, and also can be used to multiply polynomials in algebra. Includes journal prompts, homework master, extensions, Common Core standards addressed, and answer key.

Be Your Best With Briq

Mathematics Stories - HAPPY HARRY - was one of my more "radical" stories. Dividing Fractions and Simplifying Rational Expressions by division are tough for students at different levels of mathematics. I have always "inverted and multiplied" in my head. By the way, the proof of why we have to invert before we multiply (because you want to divide by 1, is too long to really explain, so we tell students ... ) That is the only "formal" algorithm that mathematicians know. Since I always did this in m

Raise the Rigor

A Complete Interactive Notes Unit Interactive Notes are popping up all over the place now. What makes this Interactive Notes unit different? Higher order thinking! For each lesson students self-assess their knowledge on the topic prior to the lesson, then use the interactive parts to learn the meat of the lesson, and finally apply their knowledge to write to explain in the W.A.M. section. ***************************************************************************** What Topics Are Covered Five
