3-5
Explore relationships among fractions through
work with the length model.
3-5
This lesson provides a hands-on approach to converting
improper fractions to mixed numbers. In
addition, students locate improper fractions on a number line. Students use
number cards and counters as manipulatives while exploring the relationship
between improper fractions and mixed numbers. Students reinforce their skills
while playing a modified version of Calculation Nation’s “Dig It.”
3-5
In this lesson,
students use operations of whole numbers and/or fractions to determine the
precise numbers of three types of dried beans needed to make salads. The use of
manipulatives and partner activities provide differentiation and support
learning for students of varying abilities.
3-5
Students will use
base ten blocks to model decimal multiplication. They will assign different
values to the different base ten blocks to explore the consistent relationship
between the types of blocks. They will also discover different factors for the
same product. These activities will help students develop a conceptual
understanding of decimal multiplication.
3-5
In this lesson, students use fraction bars to explore
how to compare sizes of fractions. They conclude with an online Calculation
Nation
® game
called Fraction Feud.
3-5
Project this lesson on a whiteboard and watch your students “number line dance” their way to fluency in estimation of products. The lesson is scaffolded to start students finding basic multiplication facts on a number line and ends with students estimating four digit products on a number line. Use the lesson to teach estimation of products or as a culmination of your own estimation of products lesson.
3-5
In this series of 3 hands-on activities, students develop and reinforce their understanding of hundredths as fractions, decimals, and percentages. Students explore using candy pieces as they physically make and connect a set/linear model to area models.
3-5, 6-8
In this lesson, students use a Venn diagram to sort prime factors of two or more positive integers. Students calculate the greatest common factor by multiplying common prime factors and develop a definition based on their exploration.
3-5, 6-8
This applet allows students to individually practice working with relationships among fractions and ways of combining fractions.
3-5
In this lesson, students build a three‑dimensional model from their two‑dimensional blueprint. In addition, they solve problems related to constructing and decorating their clubhouse.
