Which One Doesn't Belong? Free Math Activities for Grades 1-8

Free ‘Which One Doesn’t Belong?’ Activities for Your Upcoming Lesson Plans!

Are you looking for an engaging math activity to boost your warm-ups, transitions, and/or exit ticket activities?

If you’re not familiar with using ‘Which One Doesn’t Belong?’ (WODB) activities and why they are amazing for boosting student engagement in the math classroom, click here to learn everything you need to know.

I started sharing WODB activities with my students because I was struggling to find ways to get all of my students engaged, especially those who struggle with mathematics and are reluctant to participate.

I was inspired by the work of Christopher Danielson, so I started creating my own WODB activities geared towards students in elementary and middle school.

The results? My student engagement skyrocketed! Since WODB activities don’t have a single correct answer (the idea is to get students thinking mathematically and learn how to justify their answers), all of my students (even ones who rarely participate) felt comfortable sharing and getting involved.

Now I use WODB at least once a week!

Can Your Students Solve These Multiplication Table Math Puzzles?

Are you looking for some fun and engaging activities to help your kids practice and understand multiplication?

I started using multiplication table puzzles with my students every week last school year, and the results were pretty awesome, especially when it came to improving their ability to multiply and divide values without relying on memorization.

And if you're a fan of Stanford's Jo Boaler, then you know that she is a huge proponent of using visual math activities (like multiplication table puzzles) to improve student performance.

The following puzzles challenge students to use their math and reasoning skills to find the value of different symbols contained within a multiplication table.

They work like a bingo-table where the icon in each box represents the product of its corresponding column and row.

So go ahead and share the puzzles with your kiddos this week! They make for a great warm-up or cool-down activity for sparking mathematical discussion and creative problem-solving!

Multiplying Square Roots and Multiplying Radicals Explained

Learn How to Multiply Radicals and How to Multiply Square Roots in 3 Easy Steps (Free Worksheet Included)

Learn How to Multiply Radicals (and How to Multiply Square Roots) in 3 Easy Steps

Before you learn how to multiply radicals and how to multiply square roots, you need to make sure that you are familiar with the following vocabulary terms:

Radical vs. Radicand

The radical is the square root symbol and the radicand is the value inside of the radical symbol. The radicand can include numbers, variables, or both.

The Multiplication Property of Square Roots

The key to learning how to multiply radicals is understanding the multiplication property of square roots.

The property states that whenever you are multiplying radicals together, you take the product of the radicands and place them under one single radical.

For example, radical 5 times radical 3 is equal to radical 15 (because 5 times 3 equals 15).

How to Multiply Radicals and How to Multiply Square Roots Example

Now let’s take a look at an example of how to multiply radicals and how to multiply square roots in 3 easy steps.

Problem:

Step One: Simplify the Square Roots (if possible)

In this example, radical 3 and radical 15 can not be simplified, so we can leave them as they are for now.

Step Two: Multiply the Radicands Together

Now you can apply the multiplication property of square roots and multiply the radicands together. In this case, radical 3 times radical 15 is equal to radical 45 (because 3 times 15 equals 45).

Step Three: Simplify the Result (if possible)

The third and final step is to simplify the result if possible.

Can radical 45 be simplified?

The answer is yes.

Since radical 45 is equal to radical 9 times radical 5, and because radical 9 is equal to 3 (since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5 (see the diagram below for a more detailed look on how to simplify square roots).

Finally, we can conclude that the final answer is:

Box and Whisker Plots Explained in 5 Easy Steps

Box and Whisker Plot Definition

Source: Mashup Math MJ

A box and whisker plot is a visual tool that is used to graphically display the median, lower and upper quartiles, and lower and upper extremes of a set of data.

Box and whisker plots help you to see the variance of data and can be a very helpful tool.

This guide to creating and understanding box and whisker plots will provide a step-by-step tutorial along with a free box and whisker plot worksheet.

Let’s get started by looking at some basketball data!

How to Make a Box and Whisker Plot

Observe the following data set below that shares a basketball players points scored per game over a seven-game span:

Step One: The first step to creating a box and whisker plot is to arrange the values in the data set from least to greatest.

In this example, arrange the points scored per game from least to greatest.

Step Two: Identify the upper and lower extremes (the highest and lowest values in the data set).

The lower extreme is the smallest value, which is 5 in this example.

The upper extreme is the highest value, which is 32 in this example.

Step Three: Identify the median, or middle, of the data set.

In this example, the median is 17.

Step Four: Identify the upper and lower quartiles.

To find the lower quartile and the upper quartile, start by splitting the data set at the median into lower and upper regions.

The upper quartile is the median of the upper region, and the lower quartile is the median of the lower region.

In this example, the upper quartile is 20 and the lower quartile is 10.

Now we have all of the information that we will need to construct our box and whisker plot!

Step Five: Construct the Box and Whisker Plot

To construct a box and whisker plot, start by drawing a number line that fits the data set.

Start by plotting points over the number line at the lower and upper extremes, the median, and the lower and upper quartiles.

Next, construct two vertical lines through the upper and lower quartiles, and then constructing a rectangular box that encloses the median value point.

Then construct a vertical line through the median point that extends to the top and bottom of the rectangle.

This is the box in the box and whisker plot.

Finally, draw horizontal lines that connect the lower quartile to the lower extreme and the upper quartile to the upper extreme to complete the box and whisker plot.

The box and whisker plot is complete!

Two Truths and One Lie (2T1L) math activities revolve around your students being presented with three facts, images, or statements (only two of which are true). The objective is for students to identify which statement is false and justify why (verbally, in writing, or both).

2T1L activities are an excellent strategy for boosting student engagement, sparking mathematical thinking, and opening small-group or full-class discussions. They are great for warm-up and cool-down activities during the first or final minutes of class.
