22) Equivalent fraction models are important for students to have in several contexts. Identify two models and an example of how they can be used for teaching equivalence.
1. Area model - Fractions are determined based on how a part of a region or area relates to the whole area or region. Ex. Make a pie and cut into fractions. Put pieces on top to see the fraction relative to the size of the whole. Ex 2. "Pan of brownies" Have students make paper brownies like the pie above and have them put the pieces together on top of the whole making different kinds of fractions.
Name two strategies or methods for helping students to develop estimation skills. Describe how these strategies/methods would contribute to conceptual understanding.
1. Estimates that are not reasonable 2. Estimation should be a classroom activity, do it once a week. Need experience measuring and estimating.
21) Researchers have described a number of reasons that students have a tendency to struggle with fraction concepts. Name two of these reasons, and describe a method a teacher might use to address each.
1. Fractions are very universal. They can be used to measure building supplies or rooms or even used in the kitchen. This can be confusing to kids. Therefore if the teacher were to ensure students get experience with fractions in a variety of different real-life experiences, the students will understand how to apply them to everyday life. 2. Students tend to think that the top (numerator) and bottom (denominator) are two separate numbers. This can be incredibly confusing to kids that can't conceptualize them as a part of a whole number together. If you show the students real life examples, then it'll hep them be able to apply this skill outside of the classroom.
21) Name two methods that could help students develop the connection between fractions and decimals. Then describe how these methods develop conceptual understanding.
1. Have students use food for examples. Such as 40% would be how much of the pizza? 1/5 would be how much of this pie? Breaking it down into these parts can help students visualize what they are doing as well using real life situations will help them relate these problems to reality. 2. Use plant growth to show how a plant grew. If the plant grew more than 100% in a single year, you can show them in decimals and fractions how much the plant grew. This will help students relate decimals and fractions to outside of the classroom experiences.
