represent addition and subtraction operations. Challenge students
to show their understanding of addition and subtraction by using
formal number sentences (1 + 2 = 3), tallies, pictures, or number
lines drawn on paper.
Story Problems
Use the number line to help students understand basic story
problems involving key math language (in all, how many left, total,
altogether, more than, less than, etc.).
Example:
Josie read 4 books.
Lucas read 3 books.
How many books did they read in all?
Have a student stand on the number 4 to represent 4 books.
Then, discuss ways to solve the problem using the number line
(the student steps 3 places to the right for a sum of 7).
Intervention Strategies
Simple Addition: Counting on is a basic way to add a small
quantity to a large quantity. For example, to solve 4 + 3, a student
can count on three: 5, 6, 7. Have students count on (or back for
subtraction) as they step on the line.
Computation: Encourage students to draw their own number lines
when working out traditional paper-and-pencil number problems.
This helps students visualize problems and clarifies their
understanding of both the problem and solution.
Vocabulary: Correct misinterpretations of operational phrases such
as “How many left?” to prevent students from confusing them with
directional meanings.
Number Sense: Ensure that students are viewing the number line
from left to right to prevent confusion during problem-solving
activities.
Measurement: Use number lines to introduce linear measurement,
rulers, and standard units.
