High schoolers differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.

Young scholars compose groups of items up to the number 5. In this number 5 lesson plan, students also connect names to numbers, record sizes of groups, and compose and decompose groups.

Students match quantities to their number.  In this building to nine lesson, students put groups of objects together to make a group of nine.

Learners complete subtraction problems where they use goldfish crackers as their manipulatives in the problem. In this subtraction lesson plan, students use words and pictures to also show their problems.

Learners use a balance to complete subtraction problems and weigh out the items they take away. For this subtraction lesson plan, students use a pan balance and record their equations.

Young scholars estimate the amount of money they have in groups of pennies, nickels, and dimes. In this money lesson plan, students then count up the amounts they have and exchange money amounts.

Students make bar graphs and identify items in the bar graphs as being likely, certain, or impossible. In this bar graphs lesson plan, students answer questions about the bar graphs using reasoning and communication skills.

Students use objects and symbols to create original linear patterns. In this patterns lesson plan, students also translate patterns from one modality to another.
