Data Analysis and Probability

Sickle Cell Anemia Inheritance

6-8, 9-12
In this lesson, students explore the concept of genetics and inheritance. The lesson focuses on sickle cell anemia, a genetic disease that is dependent on a recessive trait. Students will perform data collection and analysis of the probability of a child of two sickle trait parents inheriting sickle cell anemia. To do this, they play a game that models how the inheritance of a disease works from parents’ genes. Later, students construct family trees with probability to determine the genotypes of family members.

Begin With Buttons

Pre-K-2

In this unit, students use buttons to explore logical and numerical relationships. The unit begins with two lessons that focus on the two basic logical thinking skills, classification, and seriation, which are the foundation for understanding numbers and number relationships. These abilities in turn form the basis for understanding addition and subtraction. ...

In the next six lessons, students explore the relationships between numbers and model addition and subtraction sentences with buttons. ...

Students will explore the operations of addition and all three meanings of subtraction (take away, comparative, and missing addend). A set model is used for both operations. ...

Comparing Connecting Cubes

Pre-K-2
In this unit, students explore five models of subtraction (counting, sets, number line, balanced equations, and inverse of addition) using connecting cubes. The lessons focus on the comparative mode of subtraction. In them, children explore the relationship between addition and subtraction, write story problems in which comparison is required, and practice the subtraction facts.

Do It with Dominoes

Pre-K-2
In this unit , students explore four models of addition (counting, number line, sets, and balanced equations) using dominoes. They also learn about the order (commutative) property, the relation between addition and subtraction, and the result of adding 0. Students also write story problems in which the operation of addition is required and begin to memorize the addition facts. In this unit, students also investigate properties of addition and represent addition in pictures.

Food Pyramid Power

Pre-K-2
In this unit, students use algebraic thinking to explore properties of addition. The food pyramid is the starting point for these explorations. Students’ ability to classify forms the basis of algebraic thinking. In this unit, students explore sorting and patterning and apply these logical processes to the operation of addition in the set model. They also construct sets of a given number and find missing addends.
