This activity incorporates coding loops with repeating pattern skills. Students will create a loop on Scratch and describe how it relates to pattern cores and repeating patterns.

 The purpose of this lesson is to help students develop their understanding of algebra using the patterns of multiplcation that occur on a hundreds board.  This is an effective strategy that will help students develop an understanding of multiples which is very crucial in 4th grade and above.  It also reinforces mutiplication as repeated addition.  This is also an effective strategy to use with English Language Learners, Special Educational Students and struggling learners because it provides a hands-on, interactive format for the whole class to see and participate.This lesson is also very engaging and it promotes most of the 5 C's: critical thinking, creative thinking, collaboration, communication, and citizenship.Use the following sites to look at 2 products that I have used from EAI and Didax.https://www.eaieducation.com/Product/504038/Make_a_Splash%e2%84%a2_120_Mat_Floor_Game.aspx (see image)https://www.didax.com/hip-hoppin-hundreds-mat.html 

Using the available commands, students will design a sequence of events that will efficiently move the student to the restroom through the obstacles on the grid.  Use repeated patterns when appropriate.  The students will work with a partner or small group to design a program to move a “student” through a classroom with obstacles.  The student will be a paper avatar.  The classroom will be a 8 by 8 grid with pictures of obstacles the student must move through to get to different destinations.  The students will try to move through with the least number of steps.  As an extension, they can rename a loop of multiple steps, and it will become one st
