One of the most important concepts introduced in pre-algebra (or algebra) is integer operations. I can distinctly remember learning "the rules" and fun little tricks to remember them. But I also remember wondering why in the world subtracting a negative means you add! So when I saw this method to introduce adding and subtracting integers, I knew I had to try it. *Please Note: This post contains affiliate links which help support the work of Keep Reading...
Investigating Exponent Properties {FREE Lesson!}
Many of the topics covered in Pre-Algebra or Algebra are taught as "rules," "properties," or "formulas" to be memorized. And while it is definitely helpful to have certain properties or formulas memorized, I think it is much more important that these Algebra facts be taught in a way that is logical and makes sense, rather than simply telling students "This is true. Now use it correctly." If you let students explore and discover math truths on Keep Reading...
Valentine’s Day Algebra Practice Pack! {FREE!}
Having taught many different levels of Algebra over the years, I always have so many ideas that I want to share with you, but not always enough time to get it created and posted! So slowly but surely I'm starting to get things together and today I'm excited to share what I hope is a fun and helpful resource for Valentine's Day! This Valentine's Day Algebra practice pack covers many different skills for students to practice and review. As I Keep Reading...
Exploring Surface Area of Pyramids and Cones!
As promised, I have another surface area lesson to share today! This builds on students' previous knowledge from the prisms and cylinders lesson to get them thinking about other three dimensional shapes: pyramids and cones. This FREE surface area of pyramids and cones investigation is a sure way to get kids thinking and better understanding area. It is also a fun, hands-on way to help them form a conceptual understanding, rather than trying to Keep Reading...
Exploring Surface Area: Hands-On Lesson!
One topic that I believe is too often rushed through, whether in pre-algebra or geometry, is the surface area of three dimensional objects. Because it is often seen as an "easy" topic where students are expected to simply "plug the numbers into the formula," it can be easy to say, "Here's the formula, GO." And while this may work for some students, especially students who have a strong foundation in geometry vocabulary and a strong understanding Keep Reading...
Making Absolute Value Clear (With FREE Printables!)
One of the math concepts that I have seen students struggle with the most, and yet seems so simple at first glance, is absolute value. It often seems that the only thing students ever "get" from an absolute value lesson is this: absolute value = make it positive. That is NOT, however, the definition of absolute value, and therefore, becomes the cause of much confusion as students try to apply and use absolute value in more complicated problems. Keep Reading...
How Much Does a Pumpkin Cost? {FREE Algebra Lesson!}
For many students, the transition from math computations in the upper elementary grades to Algebra is a challenge. Suddenly, they are having to write mathematical equations and use symbols and letters rather than just numbers. (Although hopefully they have at least been introduced to some of these things prior to formal Algebra). One way to help students ease the transition and make sense of it all is by looking at real and meaningful examples. Keep Reading...
Exploring Patterns in Pascal’s Triangle {FREE Printables!}
When I taught Algebra, there were lots of ways I loved to explore patterns with kids and help them make the connection between a number pattern, a table, a graph and an equation. One way we did that was by looking at fractals. Another really fun way to explore, play with numbers and see patterns is in Pascal's Triangle. The pattern known as Pascal's Triangle is constructed by starting with the number one at the "top" or the triangle, and Keep Reading...
Sir Cumference Lesson! {Euler’s Law}
There are so many benefits to reading and engaging with math stories. But I think students will get even more out of the story if the learning doesn't stop once the last page is read. Therefore, I have been creating activities to go along with some of my favorite math books! (If you missed the activities for Math Curse by Jon Scieszka, be sure to check it out!). Honestly, I love all the Sir Cumference books by Cindy Neuschwander. They are Keep Reading...
Math Curse Activity Pack! {FREE!}
Math stories are such a fun way to engage kids in math learning, as well as help them see math in the world around them. Stories can make math come alive and get kids excited! One of my favorite (and highly engaging) stories is Math Curse by Jon Sciezka. This hilarious tale can be enjoyed by kids of all ages. To help you incorporate this into your math curriculum, I've created this Math Curse Activity Pack! This is such a fun book, and I Keep Reading...
