Place Value Track

Place Value Track

Place Value tracks are taught to students in the Corrective Mathematics program across all four modules. Students learn about place values, read numbers as long as five digits and write these numbers with the appropriate commas. They also learn to work with numbers that include one or more zeros and identify digits belonging to the ones, tens, hundreds and thousands number columns.  

Here is an example from Exercise 5, Lesson 30 of the Addition module on page 67 of the Series Guide, in which students learn to determine numbers of tens verbally.  

• The teacher says a few numbers and the students are told to say how many tens are in each number and think about how they are written. 
• Students answer in tens for each number. 
• The teacher repeats the steps until students can read the place values in tens with no errors.  
• The teacher then calls on individual students to say the place value of numbers of tens in a randomly selected order.

An auditory signal is used for this exercise. Students can make an error in Step B by answering abruptly without thinking of ways in which the number in the tens column is written. Model-Test-Retest error correction is used to correct errors immediately when they are heard.
