Pre-K-2, 3-5
Play a matching game with different representations of equivalent items.
3-5, 6-8
Explore different representations for fractions including improper
fractions, mixed numbers, decimals, and percentages. Additionally, there
are length, area, region, and set models.
3-5
This lesson promotes problem solving and reasoning with fractions as students investigate the relationships between various parts and wholes. It also focuses on representation because students are given multiple opportunities to investigate the relative value of fractions. Students use communication skills as they work in pairs to articulate and clarify their understanding of fraction relationships.
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
In this lesson, students use a ruler to represent various fractions as lengths. This lesson builds on the work done in the previous lessons with as students use a standard instrument to measure a variety of items, including items which can be measured to the nearest half and quarter of an inch.
3-5
Students investigate the length model by working with relationship rods to find equivalent fractions. Students develop skills in reasoning and problem solving as they explain how two fractions are equivalent (the same length).
