- Key
Topics include:
- Rounding to the nearest ten
- Rounding to the nearest hundred
- Adding and subtracting two 2-digit or 3-digit numbers
- Repetitive practice using the terms "sum" and "difference" to help students memorize the definitions of those terms

- Use it as a whole class (in person) teaching tool by projecting the slides and using the movable, interactive pieces for a fun whole-class lesson.
- Use it for whole class Zoom meetings to lead a meaningful lesson.

In addition to my work in education, I also run a STEM-based Christmas Light Show business. When I'm not creating new math resources or working with teachers, I'm designing and fabricating light shows sequenced to music with my husband and our team. That business came about after our family was featured on ABC's The Great Christmas Light Fight. My son attends the University of Texas, Austin and I'm currently soaking up every last minute with my daughter, a high school senior.
