Normal Distribution Curve Reference Sheet

 

We started our statistics unit in algebra 2 and so far have reviewed box and whiskers plots, dot plots, histograms and learned about skewed data, interquartile range and experimental vs. observational studies. Last week, we started learning about normal distribution and will be on this topic for a little while. We move onto z scores tomorrow.

We gave students a simplified version of the curve with whole number percentages to make calculations easier to manage. I wanted to share this reference with you in case it would be helpful for your students, too. If you'd rather keep the decimals in the percentages, there's also a blank curve in the file.

We printed a bunch on this orange paper (the orange reminded me of that funny normal distribution ghost meme) and laminated them so that students can write on their curves while working.

You can download this normal curve reference here from my Google Drive.

Rounding Decimals Escape Room

A few weeks ago, I shared a free rounding money cheat sheet that a teacher had asked me to make. Then just last week, a neighbor asked if I could help her daughter with her rounding whole numbers homework. It seems everyone is rounding all of a sudden! 

In this post, I want to share a new rounding decimals math escape room. There's also a special code below:)

Solving equations visually using cut paper algebra tiles

Algebra tiles help make math visual for students, and paper algebra tiles take it a step further because we can cut them into fractions. In this post are a few short cut paper algebra tiles videos for solving 1-step and 2-step equations that include when x is a fraction.

This first equation is a simple 1-step equation where x is being divided by 4.

 

Next up is another 1-step equation where the coefficient of x is a negative fraction. 

Rounding Money Cheat Sheet for Middle & High School Math

A teacher emailed to ask if I could make a math cheat sheet for rounding money to the nearest cent. It took me a few weeks to come up with the format. I hope it ends up being helpful in your classroom if your students are solving rounding problems to the nearest hundredth. 

How many times have you heard, "wait, does $45.678 round to $45.67 or $45.68?" Your students are in the middle of solving compound interest problems, and suddenly you overhear an elementary skill rearing its ugly head-- rounding. Why is rounding money to the hundredths place such a sticking point for students, even older students in middle and high school? 

4 Editable New Year's Math Review Coloring Activities

Happy New Year 2026! If you're looking for a midyear review for your middle school 6th grade, 7th grade, 8th grade or algebra 1 students, there are 4 editable math review activities updated for 2026 linked below. Each comes with 20 review questions and a 2026 coloring sheet, and will be updated every year. The math reviews can be used to refresh skills or as semester 1 review when students come back from winter break. 

Each of the 4 math reviews comes with a 2026 coloring page and an editable 2-page worksheet with topics covered between back to school and the new year. 

Algebra 1 Midyear Review

Topics include:

• Multiplying binomials 
• Factoring quadratic trinomials 
• Finding parallel and perpendicular lines through given points
• Calculating slope and y-intercept from a table 
• Converting standard form equations to slope-intercept form 
• Identifying domain and range of graphs

This algebra activity is editable in PowerPoint and includes 20 questions. 

Students answer the questions on their worksheets, then color their 2026 based on the key. An answer key is included.

8th Grade Math Midyear Review

Topics include:

Domain and Range Finder Tools

Do your students struggle finding domain and range of graphs? I made a couple printable domain and range tools to help our students this year.

There are directions pointing students to look at x for domain and y for range as they drag each tool across the graphs. There are also directions printed on the tool for what to record for domain and range when a graph has an arrow.

We have always used rulers to find where graphs start and stop, but I wanted something a bit more self-teaching for our students this year. The graph cards in the photo are a free download on my blog here.

You can find the domain and range finder tools here on my website.

I also made a new domain and range of graphs cheat sheet for our students that you can find here in my drive.

UPDATE: A 3rd tool for finding increasing/decreasing intervals of graphs has been added to the file linked below.

Winter math activities and classroom décor

We're getting so close to winter break! In this post, there is a collection of winter-themed math activities that hit the standards while keeping students engaged in learning their math before and after winter break. Many of the activities below were made to double as colorful winter math bulletin board displays of student work.

Slope winter snowflake activity

The first activity is a slope winter snowflake activity where students find the slopes of lines given a table, then decorate your classroom with their finished snowflakes. Anna L's students called their slope snowflakes "slope flakes" as they worked on the slope review activity coming back from winter break.

multiplication ornaments

These multiplication ornaments make a festive math bulletin board display of student work. Students can decorate their ornaments with bows and holly after calculating their products. There are 4 blanks also included for your own multiplication problems.

Winter proportional relationships snowflakes

There's a similar set of winter proportional relationships snowflakes for younger students. students plot coordinates of proportional relationships, then determine the equation of each snowflake's line. 

Winter snowflake 2-step equations

If your students are solving 2-step equations this winter, they can practice their solving on this winter snowflake 2-step equations sheet. After solving, students will need to read the inequalities in the key to figure out which color to color each section of their snowflake.

Slopes between winter animal pictures

This winter slope activity has students calculating the slopes between winter animal pictures in the coordinate plane. The x-axis is in months, and the y-axis is in days of the month. It's a fun, low-stress way to review slope.

Multiplying decimals mittens

If your students need practice multiplying decimals, these multiplying decimals mittens make a colorful winter bulletin board display of student work.

Multiplication ornaments activity

This set or Christmas multiplication ornaments have students multiplying multi-digit numbers that then become winter classroom décor. The multiplication problems include: 2x2 digit, 2x3 digit, 1x4 digit, and 2x5 digit. There are a bunch more Christmas math activities here for middle school, high school and elementary school math topics.

Winter picture puzzles math escape room

For a digital activity, this winter picture puzzles escape room has students solving for the values of winter pictures before going on to the next puzzle. 

Winter picture puzzles math escape room

The escape room is self-checking in Google Forms, and also comes as a printable PDF for days off devices. 

Editable New Year's math review

This is year #2 of updating this editable New Year's math review. There are versions for 7th grade math, 8th grade math, and algebra, and will be updated every year. They're each editable in PowerPoint so that you can customize the activity to your students' needs.
