# Teaching Integers and Absolute Value (7th Grade)

In the 7th grade, children begin to understand the absolute value of integers and can interpret absolute value as magnitude for both positive and negative quantities in diverse real-life situations. To help students achieve mastery of integers and absolute value (7th grade level), math teachers can prepare simple strategies for their lessons. We’ve compiled a […]

# Writing and Evaluating Algebraic Expressions

When learning algebra in school, children come across many word problems. Some are simple and concise, whereas others are complex and may even resemble a short story. To solve such word problems, kids must first create algebraic expressions out of word problems. This is referred to as evaluating and writing algebraic expressions. Teachers and homeschooling […]

# Applications of the Pythagorean Theorem

I enjoy spending time with the Pythagorean Theorem. Proving it and showing how the squares of each leg add up to the square of the hypotenuse can provide a clear picture to your students.

# Rounding Game – Rounding for Seats

Students sitting in a Pre-Algebra class will have varying degrees of ability when it comes to rounding and estimating. This activity is meant to be used with those who need remedial help and to assess the overall ability of the class. It is a fun way to accomplish two things throughout the year rounding and […]

# Variables and Expressions with Dr. Seuss

This is one of my favorite lessons to teach because it is truly a pivotal point in my students math careers. Without a clear understanding of Variables students will not be able to move forward and succeed in math. In order to teach this lesson on Variables and Expressions you will need a couple of […]

# Place Value Games

What You Will Need for these Place Value Games These place value games all require one or multiple decks of index cards that each have a number from 0 to 9 on them and a decimal point on one card. How to Setup the Place Value Games Step 1: Group the students in pairs or […]

# How to Teach Multiplying Binomials – Without FOILING

I think we all know by now that teaching your students the old FOIL method for multiplying Binomials is a HUGE mistake! When you do this you are teaching them to memorize a pattern that won’t apply anywhere else when they move beyond Binomials. The majority of the lessons involving polynomials after this lesson will involve […]

# Stem and Leaf Plots – NBA MVP

There aren’t many places in the real world that Stem and Leaf Plots are used. However, the good news is the places they are used are very important. These are 3 Extremely Realistic Ways to Introduce Stem and Leaf PlotsAirports – Everyone loves going on vacation. It would be awful to go to an airport to […]

# The Pythagorean Theorem – Like You’ve Never Seen It Before

I have seen a lot of teachers teach the Pythagorean Theorem in hundreds of different ways in my over a decade of teaching math. There is one however, that I will forever use! This lesson is on the proof of the pythagorean theorem. This is THEE GREATEST WAY to Teach the Pythagorean Theorem! (There is […]

# Area of Circles – Thinking About Pi

You get one chance to introduce Pi to your students. We want to give you some pointers on how to make sure it doesn’t go over their head right of the bat. Introducing Pi You have to start this lesson by teaching them that Pi is a ratio of the Circumference of the Circle to […]

# Constructions – Kids with Sharp Objects
