Mrs. Walls' Math Blog (Week of 4.22.19)

We will begin Chapter 10: Data.  In this chapter, students will learn about collecting data, making graphs, and interpreting the data.  This chapter is very short and skills are typically grasped by students quickly and easily.  Therefore, we will be starting and finishing the chapter within the week.

Lessons this week include collecting data in a survey and record that data in a tally chart, interpreting data in picture graphs and use that information to solve problems, making picture graphs to represent data, interpreting data in bar graphs and using the information to solve problems, making bar graphs to represent data, and solving problems involving data by using the strategy make a graph.

Students will be taking their Mid-Chapter Checkpoint on Wednesday, April 24.  They will be taking their Chapter 10 Test on Monday, April 29.

Why teach this?
A tally chart provides an efficient way to record data collected in a survey.  One tally mark is made in the chart for each response given in the survey.  There is, therefore, a one-to-one correspondence between responses and tally marks.  Every fifth tally mark is made as a diagonal mark over the four preceding marks.  This convention makes it easier to count by fives instead of ones to find a total.  Children use a variety of skills as they read and interpret data in a picture graph.  THey must first be able to read and understand the elements of a picture graph: the title, the categories, the key, and the pictures indicating the data contained in the graph.  Once children understand how to read a picture graph, they will then be able to find and use information in the graph to answer questions and solve problems.  Children will solve problems involving addition and subtraction.  In this chapter, the keys for the picture graphs are limited to pictures that represent one unit.  THe use of a key builds a foundation for using keys in which each picture represents multiple units, which are taught in later grades.

Chapter 10 Vocabulary-
For each chapter, I will be providing a list of important vocabulary words related to our in class learning.  Developing student's math language is a great way to improve their problem solving skills (think of complex word problems!).
  • bar graph- a graph that uses bars to show data
  • data- information collected about people or things
  • key- a key for a picture graph tells the number that each picture or symbol represents
  • picture graph- a graph that uses pictures to show data
  • survey- a method of gathering information
