New — Multiplication with Decimals Unit. Make sense of multiplication with decimals in this new 5th grade unit. We engage prior knowledge with fractions, introduce a farmers market context, and employ dynamic models. Students move from concepts and contexts to procedures. With the unit's powerful models and cohesive instruction this challenging topic becomes visually and cognitively clear for students at all levels.

Visual Models Bring Clarity to Multiplication with Decimals

Visual models include a skip counting number line, vectors on a number line, and a segmented area model or closed array.
 

Open Array Model Gives Students a Powerful Tool

The open array gives students a powerful computational device, complete with partial products. This model exemplifies the latest research and next-generation standards.
 

Farmers Market Theme Gives Context to Lessons

The farmers market serves as a central theme. If one grape weighs 0.6 ounces, how much do 10 grapes weigh?
 

Students Create Smoothie Recipes in Real World Investigation

Don't forget the smoothies! This unit is anchored in a real world investigation that allows students to create their own smoothie recipes, making the most of multiplication with decimals. Sweet and healthy!
 

New — Understanding Decimals Unit. Students gain a deep understanding of decimals with our new 5th grade place value unit. With an underlying Olympics and fitness theme, students work with decimal values like the time it takes to run a race or the distance a student rides a bicycle to school. Students use visual models that relate decimals to fractions and whole number place value models.
