Choral Counting I
Using a 100s chart or a number line with a pointer, work with your class to count up to 100 by ones and tens. As a part of daily instruction, prompt your kindergartners to chant count from 1 to 30. Move on to 1 to 50, and then from 1 to...

Are They Similar?
Learners separate things that just appear similar from those that are actually similar. A diagram of triangles is given, and then a variety of geometric characteristics changed and the similarity of the triangles analyzed. Because the...

Triangle Congruence with Rigid Motion
Combine transformations and triangle congruence in a single activity. Scholars learn to view congruent triangles as a rigid transformation. Using triangle congruence criteria, learners identify congruent triangles and the rigid...

Popping Problems!
Turn your math lesson into a carnival game with this fun, outdoor activity. After reviewing the concept your class will be practicing briefly, split your class up into teams and head outdoors. These teams work to solve math questions and...

Congruence Through Transformations
Transform your lesson on transformations. Learners use given congruent triangles and tracing paper to determine the single transformation that carries one to the other. The concept is extended to combinations of transformations to...

How Many _______ Are In. . . ?
Help your learners gain meaningful understanding of dividing fractions using fraction models. The activity includes nine problems which are sequenced to show how the fraction division algorithm evolves. Have students use graph paper or...

Skeleton Tower
Your algebra learners build a quadratic function in this task of counting the blocks used to build objects. The arithmetic sequence that shows up brings up a shortcut to the long addition using the Gauss Method. Eventually, learners...

Comparing Fractions
Young mathematicians compare two fractions with like denominators and then move to the next level to compare fractions with unlike denominators. They will first try to use mental math to make educated guesses. There are a few guidelines...

Rabbit populations
In this real-world problem about the rapid growth of rabbit populations, learners must analyze two different scenarios and create mathematical models to represent them. They use their exponential models to answer questions about the...

Similar Triangles
Proving triangles are similar is often an exercise in applying one of the many theorems young geometers memorize, like the AA similarity criteria. But proving that the criteria themselves are valid from basic principles is a great...

Introduction to Calculus
This heady calculus text covers the subjects of differential and integral calculus with rigorous detail, culminating in a chapter of physics and engineering applications. A particular emphasis on classic proof meshes with modern graphs,...

Days and Seasons
Introduce young scholars to calendars as they practice the days of the week and four seasons. First graders complete three days-of-the-week sequences, each starting on a different day. They can reference the completed sequence example...

Extending Geometric Patterns
Which square comes next? Each of these sequences is made up of patterned squares in a continuing order. Learners examine more squares to choose which one(s) would correctly continue the pattern. None of these have very complex sequences;...

Sneaky Snake: Numbers
Find the numbers that the sneaky snakes are hiding! Using a number table, primaries determine which numbers are covered up by snakes. They write in the numbers next to the matching snake below the table, which reinforces both...

Video Game Scores
Eric and Leila's video game scores are the inspiration for writing equations with parenthesis. The numbers are purposefully large to deter the class from calculating them: rather this activity meets the standard that asks 5th graders to...

Range, Cluster, Gap and Outliers
There are a number of activities here where learners collect and record data, as well as, activities where the likelihood of an event happening is calculated given the experimental probability. Young statisticians organize information...

Assessing Reading Numbers
Youngsters develop their number sense by rote counting from one to ten. Over time, they identify the numbers on their own and no longer rely on fixed recitation. Using numerical flashcards, a teacher will randomly choose numbers from the...

Algebra...Your Second Language
Help learners translate word problems into algebraic equations. They will rewrite words using symbols and evaluate algebraic expressions using real life scenarios, animation sequences, video presentations, and activities to help students...

Counting Caterpillars
These caterpillars each have a number sequence printed on their segmented bodies, but some numbers are missing! Look at the completed caterpillars as an example, asking kids to notice a possible pattern. They should observe that the...

Congruent Triangles
Geometers prove that triangle PQR is congruent to triangle ABC by describing any combination of rotations, reflections, and translations that would prove it so. There is only this single task on the handout, but a detailed explanation of...
