Missing Addend Addition to 20 | Interactive PowerPoint | Valentine’s Day Math
This interactive PowerPoint activity helps students practice addition within 20 by finding the missing addend in a visual and engaging way. The Valentine’s Day theme makes math practice extra motivating and fun. Each task shows two groups of heart icons (two addends, up to 10 hearts each) and a given total. Some hearts are already colored, while others are missing. Students use mouse clicks to color the correct number of hearts in the second addend so that the total matches the given sum. 💡 Ho

Making the Pan Balance True
I am working with pan balances and addition problems (missing addends) and was having trouble finding extra practice for the kids.
I created this double sided worksheet for a math center where the children need to fill in the missing addend (or addends) to make the pan balance show a true equation.
I plan to have the children write out the number equation as well.

Fab Four Fact Family Practice
I used this when working with my third graders on fact families of multiplication and division... Which also works indirectly with the Commutative Property and missing values. :)
My classroom is centered around the "Fab Four" indirectly the Beatles... I use it as a reward system for students who learn their multiplication facts...

Middle School Math Review Workbook -Scaffolded Spiral Review
I made this workbook for that "extra time" after we finish our daily lesson. It includes 100 questions of the "missing pieces" that I have seen from students in past years. Including long division, operations with fractions, basic word problems, etc. My goal is to have students work on it independently and learn as they go. It would be a great resource for mini lessons or some extra practice. I added it as a Word Document, so you can change whatever you would like!
