|Title:||Comparing Fractions and Partitioning Shapes|
|Learning Target:||Students will be able to partition various quadrilateral shapes into equal shares for groups of two, four, and eight people.|
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
Read with sufficient accuracy and fluency to support comprehension.
|Title:||The Doorbell Rang|
|Lexile Reading Level:||340L|
|Description:||Each ring of the doorbell brings more friends to share the delicious cookies Ma has made. This terrific and suspenseful read-aloud picture book about friendship, sharing, and cookies can also be used to introduce basic math concepts to young children.|
|Formative Assessment Strategy:|
Students will complete the “fair share” brownie activity that can be used as an assessment. The teacher will also observe student discussion groups and will want to use an observational checklist to record which students partition the brownies equally and which students do not. The student journals could also be collected and serve as a formative assessment.
|Variations, Connections, or Follow-up Suggestions|
You can extend the lesson by introducing the fraction strip model and practice using rulers to partition the strips into various fractions.
