Here is a free sample from my 8 Rule Addition Fact Strategy resource. It is an introductory activity to help your first and second grade math students understand the concept underlying this strategy. As a prerequisite, your students need to be fluent with adding 10 to a single-digit number and counting back 2 from a given number. They should also be familiar with The 9 Rule addition fact strategy. I have included a work mat and equation cards, in color and black/ white. This introductory activity is concrete and requires multi-linking cubes (the ones that link on all sides), 2 sets of 10 in two different colors, for each participating student or pair of students.

These addition equations are covered in this resource:

• 8 + 4
• 8 + 5
• 8 + 6
• 8 + 7
• 4 + 8
• 5 + 8
• 6 + 8
• 7 + 8

This resource was crafted by Judy, a teacher with a master’s degree and more than 35 years of teaching experience.

This resource includes 5 usable pages:

• 1 page teacher information
• 1 page color open-ended cube mat
• 1 page color equation cards
• 1 page black/ white open-ended cube mat
• 1 page black/ white equation cards
