Need help with mental math in your classroom? This guide is full of tips, tricks, and examples to help the teacher encourage learners to use their brain instead of a calculator. Practice problems are included with reasons how...

Learning their multiplication facts is a big step in the education of young mathematicians. Help achieve this goal with the support of this collection of instructional materials.

Develop another way to find the equation of a line. The lesson introduces the procedure to find the equation of a line given two points on the line. Pupils determine the two points from the graph of the line.

An addition table supports third graders as they learn strategies to improve their math fluency. When finding sums greater than ten, students are taught how to first make a ten and then add on the rest. A similar method is also...

Humans have been developing number systems for thousands of years, and while they can be very different from one another, they can also share surprising similarities. Take your young mathematicians on a journey through the history...

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Have you ever gone to work when you needed to stay home but didn't because the thought of making substitute plans was too daunting? Don't feel that way anymore with a template designed for first grade equipped with general classroom...

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Young mathematicians put one foot in front of the other as they learn how to measure length in an elementary math lesson. Using paper cutouts of their own feet, children measure classroom objects as they discover the importance of...

Incorporate riddles into your math lesson by having students make tree factors and determine if the number is a prime or composite. They will also use other clues to find the answer to the riddle while sharpening their...

Find Pythagorean Triples like the ancient Babylonians. The resource presents the concept of Pythagorean Triples. It provides the system of equations the Babylonians used to calculate Pythagorean Triples more than 4,000 years ago. Pupils...

All too often stores give coupons for an item, but when you go into buy it, the item is on discount.  The store won’t take the coupon if the discount is used. So what do you do, use the coupon or take the discount? This activity...

It is easy to find the area of a triangle where the base and the height are given. But in this resource, it is up to your geometers to identify the base and height of the triangle. In fact, your pupils will learn that there are three...

A short video shows how to find the shortest distance between a line and a point on the coordinate plane. Using the fact the shortest distance is the perpendicular, the presenter shows the class how to find the intersection of the two...

Explore patterns in the multiplication table in order to deepen your third graders' understanding of this essential skill. Implement this activity as a whole-class lesson, allowing students to work in pairs or small groups to support...

Dive your class into the novel The Pinballs by Betsy Byars with the support of this reading guide. Including short answer questions, a multiple choice comprehension quiz, and extension activities, a variety of materials are...

Pupils study angle measurements between different types of angles associated with parallel lines and transversals. The independent practice asks pupils to identify the types of angles in a diagram and to determine the measure of...

Does the symmetry and transitive property apply to similarity? The 10th segment in a series of 16 presents the class with a group of explorations. The explorations have pairs show that similarity is both symmetrical and transitive....

Challenge the young mathematicians to find the exact coordinates of a dilated point. The fifth segment in a 16-part series introduces the class to the converse of the Fundamental Theorem of Similarity. Scholars use the theorem to...

Use the coordinate plane to show two figures are similar. The lesson incorporates congruence transformations and dilations to move a figure on to another figure. Pupils determine that if a similarity transformation exists...

Determine the slope when the unit rate is difficult to see. The 17th part of a 33-part series presents a situation that calls for a method to calculate the slope for any two points. It provides examples when the slope is hard to...

Capture the engagement of your young mathematicians with a collaborative graphing activity. Using a deck of zoo animal picture cards, learners select a picture from the deck, record the chosen animal on a graph,...

Here's a perfect way to introduce perfect squares. Individuals color in the diagonals of squares and record observations about patterns. They connect their diagrams to exponents of two and perfect squares.

Use a resource on which you can base your lesson plan on base 10 and scientific notation. The second installment of a 35-part module presents scholars with a review of scientific notation. After getting comfortable with...
