What is a 1-15 Chart? 

A 1-15 Number Chart is a visual representation of the numbers from 1 to 15 that is commonly used by young children while learning numbers, counting, and basic place value concepts. The number chart features the numbers 1 to 15 arranged across five columns and three rows. 

The 1-15 chart is a much smaller version of the classic hundreds chart. 

What are Number Charts Used for in the Classroom? 

Print a set of these 1-15 number charts to have in your classroom as an easy reference for students to grab. I suggest laminating the number charts for extra durability or placing them in dry erase pockets or heavy duty sheet protectors which will allow students to write and erase them over and over. 

MATH = LOVE RECOMMENDS…

I cannot imagine teaching math without my dry erase pockets! They instantly make any activity more engaging and save me countless hours at the copy machine since I can use the same class sets of copies year after year.

Here are my current go-to recommendations:

• 8.5 x 11 Inch Dry Erase Pockets from Puroma
• 11 x 17 Inch Dry Erase Pockets from C-Line Products
• Expo Dry Erase Markers

They are also a great way to help students work on their number recognition skills. You could print a set of ten frame cards for students to flip over which feature numbers written in word format or numbers represented on ten frames. As students turn over each card, they could mark the number off on their 1-15 chart. 

One of my favorite way to use number charts in the classroom is to discover patterns within the numbers. An example of this would be to have the students color all of the squares with even numbers one color and all of the squares with odd numbers another color. 

There are so many different ways to use this printable numbers chart in math centers with elementary school children. 

Need more than 15 numbers? I have also created 1-20 charts, 1-30 charts, and 1-50 charts.

Blank Number Chart 1-15

​Do your students need practicing writing their numbers from 1 to 15?

I created a set of blank charts that you can print and have students fill in. The first version of the blank 1-15 chart has the numbers 1 and 15 filled in already. Students must write in the numbers from 2 to 14. 

I also created an alternate version which has all fifteen boxes blank. 

Fill in the Blank 1-15 Number Charts

I also created a set of four different missing number 1-15 worksheets for students to use to practice writing their numbers from 1 to 15.

Some of the numbers are filled in already. Students must work to figure out what the missing numbers are. This is a fun way to fit in some number writing practice. 

Why I Created This Factor Chart 1-200

I originally created a factors chart 1-100 for my Algebra 2 and Precalculus students to use as a reference while factoring quadratic polynomials.

My students loved using this factor chart as a resource, but they often became frustrated when they would be looking for a pair of numbers that multiplied to a number that was slightly larger than 100.

To help my students out and create a more comprehensive resource for my students and yours, I decided to create a factor chart that goes from 1 to 200.

Uses for this Factor Chart 1-200

I mentioned earlier that my students use this chart as a reference for factoring quadratics. Here are some other uses for a factors chart.

• Finding the Greatest Common Factor of Two Numbers
• Finding Common Denominators of Fractions
• Factoring Quadratic Trinomials

What is a 1-50 Chart? 

A 1-50 Number Chart is a visual representation of the numbers from 1 to 50 that is commonly used by young children while learning numbers, counting, and basic place value concepts. The number chart features the numbers 1 to 50 arranged across five columns and ten rows. 

The 1-50 chart is a smaller version of the classic hundreds chart. 

Need less numbers? I have also created a 1-20 chart and 1-30 chart for classroom use.

What are Number Charts Used for in the Classroom? 

Print a set of these 1-50 number charts to have in your classroom as an easy reference for students to grab. I suggest laminating the number charts for extra durability or placing them in dry erase pockets or heavy duty sheet protectors which will allow students to write and erase them over and over.

Here are my current go-to recommendations:

• 8.5 x 11 Inch Dry Erase Pockets from Puroma
• 11 x 17 Inch Dry Erase Pockets from C-Line Products
• Expo Dry Erase Markers

These number charts can be used as an alternative to a number line. Students can model basic operations on the number chart using small manipulatives or counters. 

Since these charts go up to the number 50, they are much more suitable to use for illustrating subtracting numbers than some of the other math printables I have created. 

They are also a great way to help students work on their number recognition skills. You could make cards for students to flip over which feature numbers written in word format or numbers represented on ten frames/double ten frames. As students turn over each card, they could mark the number off on their 1-50 chart. 

One of my favorite ways to use number charts in the classroom is to discover patterns within the numbers. An example of this would be to have the students color all of the squares with even numbers one color and all of the squares with odd numbers another color. 

At the middle school or high school level, these charts could be used to explore prime numbers. 

There are so many different student activities that you could create using these 1-50 number charts. 

Blank Number Chart 1-50

You could use these number charts as a way to help students discover various number patterns. What happens if we use different colors for even and odd numbers? What happens if we color all of the multiples of 5? 

They are also a great way to help students work on their number recognition skills. You could make cards for students to flip over which feature numbers written in word format or numbers represented on ten frames/double ten frames. As students turn over each card, they could mark the number off on their 1-30 chart.

What is Pascal’s Triangle? 

Pascal’s triangle is a triangular array of numbers (specifically positive integers) named after famous French mathematician Blaise Pascal. Pascal’s triangle is used in the areas of algebra, combinatorics, and probability theory. 

The first row of Pascal’s Triangle features a single copy of the number 1. The second row features two copies of the number 1. Each subsequent row of Pascal’s Triangle starts with a 1 and ends with a 1. The numbers in the middle of the row can be generated by adding the two numbers above it. 

​The main use case for Pascal’s Triangle at the high school level and beyond is to calculate the coefficients of binomial expansion. 

Lesson Plans Involving Pascal’s Triangle

​Students are often introduced to Pascal’s Triangle in middle school. At this age level, students will not understand many of the applications of the triangle, but they are at the perfect age to begin exploring the interesting patterns that can be found inside this triangular array of numbers. 

What patterns arise in the triangle if you color only the even numbers or only the odd numbers? 

Spoiler Alert: If you color in the odd numbers on Pascal’s Triangle, you will end up creating a Sierpinski Triangle which could lead into a fun mini-unit on fractals and math art! 

Another coloring activity using Pascal’s Triangle which is worth exploring is coloring in the multiples of different numbers. For example, have one student color only the multiples of 2. Have another student color the multiples of 3. Have yet another student color the multiples of 4. 

Students will soon discover that coloring the multiples of a prime number produce very different results than coloring the multiples of a composite number. 

Other types of numbers that can be explored using Pascal’s triangle include square numbers, triangular numbers, and tetrahedral numbers. You can also do a fun lesson on the Fibonacci Sequence by having students explore of the sums of diagonals on Pascal’s Triangle. 

In the past, I have given students different types of numbers to look for on Pascal’s triangle. They colored their results, and I was able to put the Pascal’s Triangles together to create a fun math art bulletin board featuring Pascal’s Triangle to decorate our classroom. 

Pascal’s Triangle Templates

I created a set of Pascal’s Triangle templates for my own classroom, so I thought I would share them with other teachers to use as well.

What are Divisibility Rules? 

Divisibility rules are easy to memorize tests that students can use to determine if any whole number is divisible by a given number. Often, this is referred to as performing a “divisibility test.” 

Depending on what number you are looking to check for divisibility by, you might have to look at just the last digit of the number, you might have to consider the sum of the digits of the number, or you might have to do a combination of these. 

Free Download of Divisibility Rules Printable Chart

I created this printable divisibility rules chart that can be placed in a student’s notebook to serve as a reference tool throughout the school year. Divisibility rules are first taught in elementary school, but their application extends through middle school and high school. It is never too late to provide students with a divisibility rules chart as a reference tool. 

This printable divisibility rules chart is available to download as a PDF and as an editable Publisher file. In order to edit the Publisher file, you will need to make sure you have Microsoft Publisher installed on your computer.

Two Different PDF Versions of Multiplication Chart 1-40

For this printable 40×40 multiplication table, one of the printable PDFs has the perfect squares from 1 to 1600 highlighted on the main diagonal of the multiplication grid. This use of color with a purpose helps students to easily navigate the multiplication chart.

Since these charts are so large, they look quite fuzzy in the images below. Don’t worry – the printable PDF file should be crisp and clear and easy to read!

The other version of the 1-40 multiplication grid has the multiples of 5 and 10 highlighted throughout the multiplication table.

I prefer this second version with the multiples of 5 and 10 highlighted since I think it helps you keep your place on the chart since it is so large.
