Product Description
This is a 23 page flipchart used to teach and assess CCSS 1.OA.6. The standard is add and subtract within 20, demonstrating fluency for addition within 10. This flipchart focuses on the subtraction part of the standard.

The first slide is interactive with 2 decks of cards that you can click on to make different problems for practice. The page can be reset and used multiple times for continuous practice generating different problems each time. The next eleven slides are set to be containers. Students drag the number sentence to the box depending on whether or not the difference is indicated. For example, if the directions say to find all numbers whose difference is 5, then 10 - 5 will stay in the box, but 10 - 4 would bounce back out. There is one page for each difference 0-10.
Three pages are practice problems where the students write their answer and click on the box to check their answer.
The end of the flipchart is 5 questions set to be used with the expressions where students choose the correct number sentence to match the picture. The last page provides directions on how to export the assessment results to excel. Of course the flipchart and assessment questions can still be used even if you do not have Expressions.

*For practice with addition, please see my other flipchart Common Core State Standard 1.OA.6 Addition within 20.
