High School Mental Math Resources (by date, latest first)

After reading “Making Number Talks Matter” by Cathy Humphreys and Ruth Parker, I was inspired to build on their discussions of number sense.

**** I strongly recommend the book!

The goal of these activities is to ultimately get students thinking about numbers in more ways than one. When we ask them to find the amount without using pencil and paper, we ask them to find and create patterns. When I say “without counting” I mean that look they get—where they close one eye and squint and point to the numbers as they compute from their seats. Students will start to realize symmetry, groupings, and patterns.

These pages are intended for use with a projector but could be adjusted for small group instruction. The first page is intended for the initial display. Have students mentally solve the problem silently and independently. One students have an answer they can give a signal to show they have a number in mind—how you choose the signal is up to you but a simple thumbs up in front of their chest (so as not to distract or discourage their classmates) would suffice. The second page puts the same problem in the corner but leaves room for notes. Here is where you put student responses in any organized fashion you prefer—the important part here is to make sure you are recording ONLY the answers (keep your poker face!). Once you have student responses, ask students to defend their reasoning or find errors in words while you scribe their thinking on the board. This is a great opportunity for students to see that there is more than one way to approach a problem and come out with an accurate answer. As you progress, it is easy to transfer their thinking into more generalized “rules” in math.

There are 30 Multiplication problems and 30 Division problems.

These Google Slides are designed to help students engage and solidify their understanding while offering extra practice. This activity requires students to use Slope-Intercept Form of Linear Equations/Functions to graph.

Inside, students will discover a fun riddle that can only be solved by completing the practice problems!

What’s included:

• Activity sheet
• Linear Function problems in Slope-Intercept Form
• A hidden riddle for students to solve by completing the exercises
• Answer key for self-checking

What is a Surd? This is a surprisingly slippery topic. As a teacher or tutor, we might have an understanding of what one is, but there are a lot of loopholes, traps and exceptions. This poster helps! We have found in our research that explanations of Surds often omit certain pieces of important information in order to generate a simpler understanding, only for the student to be told that there are some exceptions to the rules. This poster therefore aims to set a firm grounding on which to build an understanding of surds without having to navigate through the maze of exceptions and loopholes.

A simple skills poster that aims to explain, in simple terms, what an Irrational Number is. One important distinction of irrational numbers, is that even if a number sometimes might go on to infinity, it doesn't mean that it is an irrational number. This poster aims to help students understand this.

A great end of year, seasonal game that still has educational merit. Suitable for all ages. This game is available in a 5 for 3 bundle. It is a game designed to explore probabilities, and how they change as time goes on. But can also be played just for fun as a way to develop strategic thinking. There are varied numbers of weather cards, and you use your knowledge of their probabilities to prepare yourself with items to go out in that weather. If a rain card is turned over, and you are prepared with an umbrella, well done! You keep your Item. But if a sunny card is turned over, and you have an umbrella, oh no! You lose your item. The winner is the last person to remain in the game at the very end. The game is playable in 2 different ways, independent and dependent probabilities, as defined by removing completely or returning and reshuffling the weather cards as you play. Both give great play experiences. We have already played this game with tutees, and they say it's our best game so far! Purchase it to find out why. It comes with easy-cut guides, full cheat sheets and probability tracking pages for players to keep track as cards are played and revealed. Makes for great fun, and powerful learning. This card game is also available in a bundle of 5 games for the price of 3. For savings, click here to see.
