In this Cyberchase video segment, the CyberSquad must locate each other using a map's grid to construct a coordinate system using letters and numbers.
The Rational Number Project (RNP) advocates teaching fractions using a model that emphasizes multiple representations and connections among different representations.
Initial Fraction Ideas include developing meaning for fractions using a part-whole model, constructing informal ordering strategies based on mental representations for fractions, creating meaning for equivalence concretely, and adding and subtracting fractions using concrete models. Initial Fraction Ideas do not include formal algorithms, and instruction with formal algorithms was not part of this original RNP curriculum module.
Students use a virtual protractor to measure a variety of angles after going through a short introduction of how to use a protractor.
Sara and Carlos give us their take on mental math, student-led solutions, and class culture in Jen Sauls class. Carlos talks about what it feels like to present a solution in front of the class.
In this activity, students will test whether the color of a material affects how much heat it absorbs.
This task requires students to represent fractions on a number line.
Students work in pairs to measure length by lining up cubes along the longest side of an item. They count and record length by counting the number of cubes.
The purpose of this task is to address the concept of opportunity cost through a real world context involving money.
The first of these word problems is a multiplication problem involving equal-sized groups. The next two reflect the two related division problems, namely, "How many groups?" and "How many in each group?"
Both of the questions in this task are solved by the division problem 12Ö3 but what happens to the ribbon is different in each case.
When students plot irrational numbers on the number line, it helps reinforce the idea that they fit into a number system that includes the more familiar integer and rational numbers.
In this scavenger hunt games students are given the task of finding and identifying real-world shapes in their environment.
The purpose of this task is for students to select 2 numbers from a set that sum to 5 (or any other number).
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

In this video segment from Cyberchase, Digit and the CyberSquad learn that equations are balanced when the same number is on each side. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: One day, Frog and Toad were sitting together on a lily pad. Some lily pads were in a line across the pond. In the morning, Frog hopped three lily pads ...
This task suggests methods of introducing and continuing choral counting in the classroom.
In this activity students become familiar with the math vocabulary more/less/same and most/least as they count and compare small groups.
In this video from Cyberchase, the CyberSquad searches for a kidnapper using their only clues: a footprint and a handprint. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.
