4.MD.4 Make a line plot to display a data set of measurements in fractions of a unit (1/2,1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots.
In this unit, students will apply their understanding of fractions when plotting the different fractions on a line plot diagram. Students will be measuring and plotting different objects to an eighth of an inch. Students will also be using these different skills to solve problems using the information provided.
Students will build on their understanding of fractions from 3rd grade to make sense of decimals when comparing their equivalency. They are expected to use a variety of models to support their reasoning about numbers.

Questions to Ask When Helping Your Child with Math Homework
Keep in mind that homework in elementary schools is designed as practice. If your child is having problems, please let the classroom teacher know. When helping your child with his/her math homework, you don’t have to know all the answers! Instead, we encourage you to ask probing questions so your child can work through the challenges independently.
What is the problem you’re working on?
What do the directions say?
What do you already know that can help you solve the problem?
What have you done so far and where are you stuck?
Where can we find help in your notes?
Are there manipulatives, pictures, or models that would help?
Can you explain what you did in class today?
Did your teacher work examples that you could use?
Can you go onto another problem & come back to this one later?
Can you mark this problem so you can ask the teacher for an explanation tomorrow?
