6-8, 9-12
This grades 7-12 activity allows students to look for patterns within the given data. After looking at the pattern, the student should be able to form generalizations for the problem. Furthermore, this activity sharpens the algebraic skills of the students. The problem sharpens visualization skills.
3-5, 6-8
Explore different representations for fractions including improper
fractions, mixed numbers, decimals, and percentages. Additionally, there
are length, area, region, and set models.
3-5
This lesson builds on the previous two lessons by focusing on the identification of fractional parts of a region and by recording them in standard form. Students continue to develop communication skills by working together to express their understanding of fraction relationships and to record fractions in written form.
3-5
This lesson promotes problem solving and reasoning with fractions as students investigate the relationships between various parts and wholes. It also focuses on representation because students are given multiple opportunities to investigate the relative value of fractions. Students use communication skills as they work in pairs to articulate and clarify their understanding of fraction relationships.
9-12
Explore geometric sequences and exponential functions by
considering the placement of frets on stringed instruments.
3-5
Focus
on the role of numbers and language in real-world situations.
3-5
Understand fractions when they are represented as a part of
a region.
3-5
Explore relationships among fractions through
work with the length model.
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.
3-5
This lesson provides a hands-on approach to converting
improper fractions to mixed numbers. In
addition, students locate improper fractions on a number line. Students use
number cards and counters as manipulatives while exploring the relationship
between improper fractions and mixed numbers. Students reinforce their skills
while playing a modified version of Calculation Nation’s “Dig It.”
