Based on an MTLT article, the authors implement a coordinated series of well-connected number talks that allow for students to make sense of a variety of strategies that provide “flexibility” in their mathematical reasoning when comparing fractions.
3-5
This lesson is based on the MTLT article, “Playing with Fractions” by Juli K. Dixon, Treshonda Rutledge, Jennifer C. Caton, and Edward C. Nolan. In this lesson students model fractions with a fraction kit and reason about adding fractions with unlike denominators. 3-5, 6-8
Students discover the
relationships between area and perimeter as they prep for playing Square Off, a
wonderful Calculation Nation
®
game. This lesson helps students understand the math of area and perimeter, which
will help to maximize their scores when playing the game. Creating human-sized
rectangles and working with geoboards provide concrete experiences before
moving on to pictorial and abstract work with area and perimeter of rectangles.
Pre-K-2, 3-5
Play a matching game with different representations of equivalent items.
3-5, 6-8
Using the online game Deep Sea Duel, students play a card game against Okta. The objective is to choose cards so that some subset of three cards within their hand has a particular sum. Students will play several variations of the game, attempt to identify a winning strategy, and compare the game to other games that they know.
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 builds on the previous two lessons by focusing on the identification of fractional parts of a region and by recording them in standard form. Students continue to develop communication skills by working together to express their understanding of fraction relationships and to record fractions in written form.
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
Focus
on the role of numbers and language in real-world situations.
3-5
Understand fractions when they are represented as a part of
a region.
