This word problem asks students to think about fractions.
This task involves fraction multiplication and can be solved with pictures or number lines.
The purpose of this task is to have students add fractions with unlike denominators and divide a unit fraction by a whole number.
In this challenging instructional task students relate addition and subtraction problems to money and to situations and goals related to saving money.
Students learn how different characteristics of shapes—side lengths, perimeter and area—change when the shapes are scaled, either enlarged or reduced. Student pairs conduct a “scaling investigation” to measure and calculate shape dimensions (rectangle, quarter circle, triangle; lengths, perimeters, areas) from a bedroom floorplan provided at three scales. They analyze their data to notice the mathematical relationships that hold true during the scaling process. They see how this can be useful in real-world situations like when engineers design wearable or implantable biosensors. This prepares students for the associated activity in which they use this knowledge to help them reduce or enlarge their drawings as part of the process of designing their own wearables products. Pre/post-activity quizzes, a worksheet and wrap-up concepts handout are provided.
This word problem may be used for instructional or assessment purposes, depending on where students are in their understanding of addition and how the teacher supports them.
The purpose of this task is to help students see that 4_(9+2) is four times as big as (9+2). Though this task may seem very simple, it provides students and teachers with a very useful visual for interpreting an expression without evaluating it.
