Christmas tree algorithm
This is an unplugged coding activity. It is an exercise that teaches the following of an algorithm. The algorithm contains all the control structures: sequences, decisions and loops. It is important for children to identify each structure and to notice the precision of the instructions. In the end children will create a christmas tree by following the instructions.

Subtraction Algorithms for all grades
This file contains the notes I took at the NCTM Conference in Chicago. I attended a presentation on Subtraction by Frances Stern. She taught various ways to subtract with regrouping. My most favorite to use in class is the number line and France's way on pages 6-7. The France way is what I refer to in my class as "Give, Give It Back"...It's SO MUCH EASIER TO TEACH AND UNDERSTAND than the Traditional U.S. way. I don't know where this has been all my life. Please give it a try! It takes some pract

Addition and Subtraction Strategy Posters
These posters are designed to be displayed in your classroom to show the different ways your students can add and subtract. They are great alternatives to teaching the traditional algorithm, especially since it can be so difficult to understand. These strategies can also help with mental math strategies as well.

This is a full presentation for parents to help them understand our "new" problem-solving strategies and help their kids with their work, as we transition to the Common Core. So often, I have parents say things like, "I have NO idea what my child is doing with all those tally marks," or, "Why aren't you teaching the "up and down" (algorithm)?" We didn't learn to add and subtract this way and it's the #1 thing parents are confused about at conferences. I included a quick tips cheat sheet for pa

GRAPH PAPER
Graph coloring is a method of coloring the vertices or edges of a graph such that no two adjacent vertices or edges have the same color. It is often used in scheduling and resource allocation problems, as well as in solving problems in graph theory, such as the Four Color Theorem. The goal of graph coloring is to minimize the number of colors used, while still satisfying the condition that no two adjacent vertices or edges have the same color. There are various algorithms and heuristics that can

Daily/Weekly Assignment Homework Sheet
This is a user friendly, multi-subject homework "helper". Homework assignments can be a time consuming part of the day. Often students also have questions over the homework when they arrive home. I designed this to go along side the weekly homework agenda. Starting the week, teachers can give an example in writing and math of the concepts being taught, as well as weekly spelling and vocabulary words. Students can copy this into their homework "helper" to refer to while doing weekly homework.
