3-5
In the second lesson of this unit, students pose and refine questions that can be addressed with numerical data. They consider aspects of data collection such as how to obtain measurements and record the data they collect. They represent and analyze the ordered numerical data by describing the shape and important features of a set of data and compare related data sets, with an emphasis on how the data are distributed. In collecting data, students measure with standard units and carry out simple unit conversions, such as from centimeters to meters or feet to inches.
3-5
In the final lesson of this unit, students recognize differences in representing and analyzing categorical and numerical data. Students also identify examples of each type of data.
3-5
In this interactive geometry investigation, students explore geometric solids and their properties. Specifically, students count the number of faces, edges, and corners (vertices) in various solids.
Pre-K-2
Problems such as those in this activity help develop what students already know in preparation for writing equations and learning ways to solve for variables. Students use mathematical models to explore quantitative relationships. When presented with pictures of pan balances with one or more objects in each pan, they communicate relationships between the weights of the objects by comparing the balanced and unbalanced pans.
9-12
As you review student work in this unit, it is important to remember
the mathematical objectives/expectations of this Unit Plan that are
stated in
Principles and Standards for School Mathematics.
Pre-K-2
Students sort objects and observe the properties others use for sorting. This activity helps students understand and connect many mathematical ideas. By labeling their sorts, students connect number with sets of objects that compose the pattern.
Pre-K-2
Students build on prior knowledge of sorting and classifying when they recognize sorts and name rules for sorting. They identify common properties in the classroom environment and make, explain, and defend conjectures to extend their knowledge.
Pre-K-2
This lesson assesses students' understanding of patterns. It measures their ability to create, extend, and interpret patterns in multiple ways.
Pre-K-2
In this lesson, students make groups of zero to 5 objects, connect number names to the groups, compose and decompose numbers, and use numerals to record the size of a group. Visual, auditory, and kinesthetic activities are used to help students begin to acquire a sense of number.
Pre-K-2
As students construct groups of a given size, recognize the number in the group, and record that number in numerals, they learn the number words through 5 in order (namely, to rote count), and develop the ability to count rationally.
