0-1000 Hundred Boards *EDITABLE*
Help learners visualize addition and subtraction and 3 digit number magnitude before introducing abstract algorithms. These simple boards are editable to fit your needs. Glue them together into one long board or use them individually. I created them because I just couldn't find them anywhere on the internet! Print out on cardstock and laminate for durability.

Division anchor Charts
These charts offer a memory help and anchor to remember the complicated steps of division using the Standard Algorithm. My students love these charts. Each chart features a colorful burger with the steps and saying. Does (divide) McDonald's (multiply) Sell (subtract) cheese (check) burgers (bring down). In the past, I have placed magnets on the back and then we move each step as we complete it so they can clearly see what comes next.

Cosmo's Minus Method (Poster / Handout)
Cosmo's Minus Method is an adaptation of Cramer's Rule I made for my Algebra 2 class. I wanted them to have this algorithm as an alternative to substitution or elimination to solve moderately difficult systems of 2 linear equations in standard form. I chose not to call it Cramer's Rule because a quick google search would reveal how to use Cramer's Rule with the available TI-84 Graphing Calculators. Also, the title of the algorithm "Cosmo's Minus Method" comes from the name of the crazy neighbor

Subtraction- Two Digit Numbers with Common Core Strategies
Teaching Common Core Math makes sense. Teaching with meaning, without memorization. This power point has seven strategies to use with common core instruction. These methods encourage students to solve problems without the traditional algorithm. Post it on your website for parents to assist their children, use it in the classroom, print it for student as they go on vacation, they can be posters, or at a center, or even to assist with student math journals.
