# Positively Practicing Prime and Composite Numbers Plus Order of Operations Project Using Google Slides

Saturday, October 10, 2015
Happy Weekend Everyone!

This week I have a lot to share with you! First off, during our Enrichment and Intervention time, students worked on an All About Me project using Google Slides.

I love the idea of taking facts about yourself and turning them into equations.  I saw this idea on pinterest but the product was on poster board or chart paper.  So I decided to turn it into a digital presentation using Google Slides.  Students were to create equations using at least three steps including parentheses or brackets to represent the numbers that are about them.   Here are a couple of examples:

Students followed a simple guideline and rubric.  To get your own copy of the rubric and guideline sheet click HERE.

I love how students are so great at using Google Slides.  The students love to add graphics, transitions and animations! It also makes grading so easy too! I cannot imagine taking 68 poster boards home!

Prime and Composite Activities

Last Friday, we had an introduction to Prime and Composite numbers.  You can check out the introduction activity in last weeks blog.
On Monday, we learned about Eratosthenes and his sieve process for finding prime numbers.  We colored a blank chart that I pulled from the internet on worksheets.com.  Click HERE for a blank chart.
On Tuesday, we looked at the sieve and we created generalizations.  Students used Padlet to share their conclusions.  These are just a couple screen shots that I took while we were completing the activity.

I like using Padlet, because it is an easy, colorful way to share ideas.  The board is live and students can get immediate feedback from me.  Reluctant students can be supported by looking at others before typing their ideas.

After we formed our ideas, we created and journaled our Rules for Composite numbers.  The rules that we came up with use multiplies and divisibility.

We used those rules the next day to test numbers.  Students worked in pairs to test numbers to see if the number was prime or composite.  Students used a checklist that had the Rules of Composite numbers listed.  Using a QR code reader students received immediate feedback.

If you would like your own copy of the checklist and number cards including QR codes, click HERE to visit my TpT store!

Two very fun Ipad Apps that I love to practice Prime and Composite numbers are Panasonic Prime Smash and Ninja Chicken.  Students love these apps! So much FUN!!!

I would love to hear from any one who uses the activities listed here! Please comment when you can or give me feedback :)

Until next week!

Peace, Love and Math-
