Keeping It All Together

3-5
By playing card games and using the The Product Game applet, students practice the multiplication facts. As students continue to master their facts, the teacher closely monitors their progress.

What Counties Are Your Favorite?

3-5
Students use their knowledge from the previous lesson to gather data on ten of their favorite counties (places they might like to live, visit, etc.) within a specific state. Students will hone their place value skills by representing numbers in various ways including standard, written, and expanded form.

Spreadsheets and Census Data

3-5
Students organize the data collected about county populations into a spreadsheet and create a graph to help them better understand the data.

Comparing Counties

3-5

Students use the data from previous lessons to find the range, median, and mode of the populations. They then compare their data with their partner's data.

As a culminating activity, this lesson combines the data and activities performed during this unit. Students are involved in class discussions and comparisons of the population data.

Eggsactly with a Dozen Eggs

3-5
Students begin to examine fractions as part of a set. This lesson helps students develop skill in problem solving and reasoning as they examine relationships among the fractions used to describe part of a set of 12.

Eggsactly Equivalent

3-5
Students use twelve eggs to identify equivalent fractions. Construction paper cutouts are used as a physical model to represent various fractions of the set of eggs, for example, 1/12, 1/6, and 1/3. Students investigate relationships among fractions that are equivalent.

Another Look at the Set Model using Attribute Pieces

3-5
The previous lessons focused on the set model where all objects in the set are the same size and shape. Students also need work with sets in which the objects “look” different. In the real world, we are often faced with fraction situations where the objects in the set are not identical. For this lesson, students use fractions to describe a set of attribute pieces. Students develop skill in problem solving and reasoning as they think about their set and how to create new sets given specific fractional characteristics.
