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.
6-8
In this lesson, students will integrate science and math, exploring how neutralization reactions can help us understand that the sum of any number and its additive inverse is zero. 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. 6-8
Students learn about ratios, including the “Golden Ratio”, a ratio of length to width that can be found in art, architecture, and nature. Students examine different ratios to determine whether the Golden Ratio can be found in the human body.
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.
6-8
Using two online activities, students use ratios and percents to compare population density and explore various statistical measures.
6-8
Develop students' understanding of ratio, proportion, greatest common factor and
least common multiple.
