My name is Peter Sacheli, and I am the Math Intervention Teacher at Walt Disney Elementary.  This website is intended to be a resource for teachers, parents and students.

     To the left you will find information about what students are learning in math.  Click on the grade level you are interested in and then on the topic your child is studying.  You will find a brief summary of the topic followed by family letters.  Please contact your child's teacher if you are unsure of the current topic being studied.  

     Each Investigations unit includes at least 2 letters for parents.  The first titled "About the Mathematics in This Unit" describes what your child should learn and be able to do by the end of the unit.  The second letter titled "Related Activities to Try at Home" offers suggestions for  activities, games and literary resources to use with your child.  Some units also include additional letters about homework and basic fact practice.

         Feel free to contact me if you have questions.
