Families of Parallel Lines and the Circumference of the Earth
How do you fit a tape measure around the Earth? No need if you know a little geometry! Pupils begin by extending their understanding of the Side Splitter Theorem to a transversal cut by parallel lines. Once they identify the proportional...

Phoneme Blending Accuracy (Mico Version)
Which word is Mico trying to say? A puppet helps make phoneme blending fun as you challenge your scholars to blend segmented words. Mico (or a puppet of your choice) has trouble saying words without separating the phonemes. Using the...

Reintroduce an Irregular Word
Some words are tricky. Can your scholars quickly recognize irregularly spelled words? Write the word was on the board (or any irregular word you'd like to practice), touching each letter as scholars segment the phonemes. Explain that the...

Parallel Lines Cut by a Transversal
Parallel lines seem so right for each other. It's too bad they'll never, ever meet. Learners use tracing paper to discover relationships among angles formed by two parallel lines cut by a transversal. They apply this information to find...

Blending Syllables Name Game
What a fun way to practice segmenting words into syllables! Engage learners by using their own names, spoken by Mico the puppet (or one of your favorites). Mico announces names slowly, syllable by syllable. If scholars have a...

Fundamental Theorem of Similarity (FTS)
How do dilated line segments relate? Lead the class in an activity to determine the relationship between line segments and their dilated images. In the fourth section in a unit of 16, pupils discover the dilated line segments are...

Proportional Segments Between Parallel Lines
Students identify similar triangles. In this proportional segments lesson, students identify corresponding sides, set up ratios, and find the length of the missing side of a triangle. They use the parallel/proportionality conjecture to...

The Counting Caterpillar
A daily counting routine builds a caterpillar with 100 body segments (marked with symbols to indicate 2s, 5s, and 10s) by the 100th day of school. Provides structured repetition as part of the morning routine so that by 100th day,...

Searching for Angles and Lines
Pupils work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

I Can Use a Worm to Count
Kindergarteners use worms, puppets or other props to practice counting to 100. First, they listen to a read aloud of Count Worms by Roger Hargeaves. A worm pattern is used to count to 100, with each segment of the worm representing a...

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...

More About Similar Triangles
Determine whether two triangles are similar. The lesson presents opportunities for pupils to find the criterion needed to show that two triangles are similar. Scholars use the definition of similarity to find any missing side...
