PRODUCT DESCRIPTION

Since many students do not know their multiplication tables, reducing fractions is almost an impossible task. The divisibility rules, if learned and understood, can be an excellent math tool. This resource contains four easy to understand divisibility rules and includes the rules for 1, 5, and 10 as well as the digital root rules for 3, 6, and 9. A clarification of what digital root is and how to find it is explained. Also contained in the resource is a dividing check-off list for student use.

I have used this successfully with students who have difficulty reducing fractions. Download the preview to view the first divisibility rule plus three samples from the student check off list.

Once my students understand and can use these rules correctly, they have little trouble when it comes to reducing fractions. I trust you will find this true as well.

I'll try this with my adult GED students. Unfortunately, many of them have never learned their times tables, so reducing is problematic. Hope this helps!
On  August 11, 2012Scipi answered:
I, too, have the same problem. I teach remedial math college students and have found that my Pattern Stick activities help with this.

My remedial math college students found this to be a very useful tool. Many had never been taught the divisibility rules. I hope you have great success. Let me know how it works in your classroom.

I sure wish I would have had a teacher like you when I was in school! Math was ALWAYS hard for me and you make it seem so fun! I am going to save this and pass it on to one of my colleagues who is also a teacher who makes math come alive for her students! Thank you!

Great summary chart of the divisibility rules! Of course, the real "root of the problem" is that they did not master the multiplication/division facts way-back-when! Just another reminder that as teachers, we work with what we're given and continue to find new and creative ways to teach!

I was helping my nephew prepare for a test just the other day and would have loved such a succinct copy of these rules then! I will certainly keep them on hand for my intervention Maths pupils - just the sort of thing they need! Thank you for a great product!
