Printable "Mathy" Math Bulletin Board Borders

A math word wall is another great use of math bulletin board space. In this word walls post there are math word wall ideas for 2nd grade through algebra 2.

There are a lot of hidden costs to owning a car, costs that students may not think about when they are dreaming of driving themselves around. In this buy a car project, students learn about the costs associated with buying and owning a car so that they can be prepared when the time comes to buy their own car.

### Fun Exponent Rules Activities

Are you getting ready to teach the laws of exponents and are looking for a few fun exponent rules activities? In this post I want to share the way I have taught patterns of exponents to arrive at 1, 0, negative and fraction exponents, as well as a few printable and digital exponent rules activities.

### "2 Truths and a Lie" Error Analysis Math Activities

In this post you'll find "2 truths and a lie" math activities, each with error analysis questions built right in. Every activity is set up the same way-- find the error (the "lie") on each card, then correct the error on the student answer sheet. Students get practice identifying math errors in the context of different math topics, and then with fixing those errors.

Here is the first card from an integer operations "2 truths and a lie" error analysis activity. There are 3 integer operations problems on the card, along with 3 statements comparing the answers. Students solve the 3 problems then figure out which statement is the "lie". Students then fix the lie on their answer sheet.

For this slope "2 truths and a lie", students are presented with a graph, a table and a pair of coordinates, as well as 3 statements about each representation's slope. Students need to figure out which of the 3 statements is the lie, then correct that lie on their answer sheet.

Students identify incorrect statements about zeros, vertex, axis of symmetry, and/or y-intercept in this key features of quadratic graphs "2 truths and a lie". All functions in the activity are factorable.

### Fun Activities for Building Data Literacy

Everywhere we look, there is data to interpret. There is data about sports, elections, health and trends in our society. Learning how to read and organize this data is important and empowering to students as they make their way through their education.

Before becoming a teacher, I worked in the environmental consulting field between leaky gas stations and the Department of Environmental Protection. Part of my job was to collect data from soil and water samples at gas stations, interpret this data and report on it. I learned at this job that data interpretation is more subjective than I had thought. For example, dropping one more monitoring well into the groundwater upstream from a leaking tank will drop the overall average of the amount of gasoline in the groundwater at a leaky gas station. I lasted 3 years in that field before making the move to teaching. It wasn't for me.

And then there's the difference between mean and median when it comes to home prices and pay. Often the median is given in these situations so that outliers don't throw off the data making the numbers appear greater than they are. Interpreting this data and talking about the differences makes for interesting classroom discussion.

In this post I want to share a few fun activities you can use in your classroom to teach data analysis.

The first is a mean, median, mode and range digital math escape room activity. Students must unlock 5 locks by finding mean, median, mode and range in 5 sets of data. Questions are grouped 4 per puzzle, resulting in five 4-letter codes that will unlock all 5 locks.

This one also comes in a black and white printable version in the same file if you'd like your students to work on paper.

Next is a box and whiskers vocabulary sort where students sort 18 vocabulary terms onto the box plot for median, outlier, upper extreme, lower extreme, quartiles and interquartile range (I.Q.R.), then identify mean, mode and range given the box plot's data.

Many professions require some level of data literacy. Whether in STEM fields, business, healthcare, social sciences, and even in the arts, the ability to work with data is an increasingly valuable skill for students to learn.

Data presented as real-world problems encourages students to apply their problem solving skills and build insights into the data. This two way tables digital math escape room activity gives students practice analyzing and evaluating the data presented in two way tables. Students find missing table values, answer "and" and "or" questions and calculate percentages represented by the data in this activity. A printable version is also included.

Next is a mean, median, mode and range math pennant activity that doubles as classroom décor when students finish the activity. Students find mean, median, mode and range given either 5, 6, 7, 8, 9, or 10 single and double-digit numbers of data. Some answers require rounding.

Students follow a stock for a week, calculate the daily and weekly percent change in price, estimate a line of fit for their scatter plot, find the slope and equation of their line of fit and write a final analysis of their data in this stock market project. Above is my student Sam's final project and written analysis of the data he collected. We did this project in our algebra class to cover percent change. It's also a nice project for a consumer math class.

In this probability digital math escape room activity, student figure out the simple or compound probability in 20 scenarios. Students find the probability of either one or two events in each question. Questions are grouped 4 per puzzle, resulting in five 4-letter codes that will unlock all 5 locks.

If you're looking for probability activities, I just recently made a "2 truths and a lie" error analysis activity for probability. Students have to figure out which of the 3 statements is wrong (the "lie") and correct the lie on their answer sheet.

Students analyze different depictions of data to find mean, median, mode, range, totals and percentages in this data math pennant activity. Data is presented in tables, line plots, line graphs, bar graphs, histograms, box and whiskers plots, pie chars and sets of numbers. Students can hang their finished pennants to show what they know as part of your classroom décor.

This line plots digital math escape room comes in both self-checking digital in Google Forms and in black and white printable PDF. It asks students to analyze and answer questions about the data shown in each line plot.

And lastly, data representations on a 6th grade math word wall including bar graph, skew, box plot, mean, median, mode, range, circle graph, histogram, dot plot, stem & leaf and frequency table. The stem & leaf and the frequency table both use the same data (the party data in the middle) so that students can see the same data represented differently. This is also true for the circle graph and the histogram, and with the box plot and the dot plot.

### Simple ways to encourage productive struggle in the math classroom

I had been considering making a meatloaf, so looked up a recipe online that called for 2 pounds of ground meat. Because it would be my first meatloaf, and because I only have 1 pound of ground beef in the refrigerator, I started mentally halving all of the ingredients to get a feel for the recipe.

The recipe called for 3/4 of a cup of breadcrumbs, so I found myself mentally halving this fraction, then thinking about how I mentally halved the fraction, then wondering how others may mentally halve the fraction. So I took to Facebook to ask how others would do this:

For such a seemingly straightforward problem, there was a wide variety of answers. Here are some of them:

### Finding Percent of a Number Cheat Sheet

Knowing how to calculate the percentage of a number is pretty much the basis of consumer math. This skill comes up when calculating interest, tips at restaurants, discounts from coupons, tax on purchased items and with budgeting. It's such a simple but important skill for students to learn and really become comfortable with before graduation.

In this post, I want to share a finding percentage of a number handout for your students.

I recently posted a cheat sheet on Facebook and got a comment about another cheat sheet I had shared some time ago in our consumer math Facebook group. It's a sheet showing students how to find a percentage of a number by dividing by 2 to find 50%, dividing by 4 to find 25%, etc. I had completely forgotten to ever share the sheet here on my blog, so wanted to write this short post sharing it from my Google Drive.

After sharing the sheet in the Facebook group, I got feedback to add 1% to the sheet. So when you download it, how to find 1% will also be there.

### Percent activities

Students unlock 5 locks by finding percents in this tax, tip and discounts digital math escape room activity. The activity comes digital in Google Forms and printable PDF.

This converting fraction, decimal percent digital math escape room activity has students converting the different forms: fractions to decimals, decimals to percents, percents to decimals, decimals to fractions and fractions to percents.

This percent change task cards activity sparks a lot of conversations about how prices have changed over the years. Students calculate and compare percent change between past and present costs of items.

Students practice finding percent change on this 1-page percent change coloring activity sheet.

### 2 Pi Day digital math escape room activities

Today is Pi Day so I wanted to share a couple digital activity ideas. Both also come in print, if you prefer having your students work on paper.

The first is a Pi Day digital math escape room for middle school where students find either the area or the circumference of a circle, given diameter or radius. Students calculate their answers then type the correct 4-letter code to move to the next puzzle.

The next is a Pi Day digital math escape room for older kids. In some of the problems, students are asked to find the diameter or radius, given circumference or area. The correct 4-letter code will unlock the next puzzle.

My husband forwarded the Morning Brew newsletter to me this morning with this absolutely astounding story about Akira Haraguchi memorizing 100,000 digits of pi. 100 digits would be impressive, but 100,000?! The short article mentions him "mentally linking each digit with a syllable and creating a collection of epic stories from the words those syllables formed."😲
