Explore fractions on a number line, and create a KWL chart about number lines! Your elementary math class can identify where fractions belong on a number line and then use black line sentence strips to create fraction number lines.
Administer a learning activity that challenges your class to use a number line in the form of lily pads. This is a great way to connect learners from using pictures to add, to using a number line to add. Learners are instructed to display the number of hops that Toad and Frog take during their journey on a number line. Young mathematicians are literally counting the hops on the lily pads and transferring that knowledge to hops on a number line. Ideal for an in-class activity or homework assignment.
Guide your kindergartners to create memorable, colorful number lines that they will use throughout the school year. Using sentence strip and a black marker or card stock printed in a teachers font, create traceable numbers from 1 to 20 (see example on the lesson plan). Give each child a number line and using five or six different colored crayons guide them to trace over all the numbers with each color. Laminate the number lines and put them on each child's desk or have them readily available. Creating the number lines will support motor and number identification skills. The number line will have more personal meaning to each learner than a pre-made one, and can be used as a tool throughout the year.
Students solve addition and subtraction problems using strings of beads and number lines. They mentally perform addition and subtraction problems, and write and solve story problems involving whole numbers.
Second graders count and locate numbers on a number line. Given a quantity of blocks, 2nd graders count the blocks and identify the number on the number line. The class discusses counting strategies, such as counting by ten.
Students explore the concept of locating rational numbers on a number line. In this rational numbers activity, students change improper fractions to mixed numbers to determine where on a number line the rational number belongs. Students use straight edges and compasses to place rational numbers on the number line.
A unique approach to reviewing number lines and how to locate different values on them, this worksheet poses several questions that require written answers rather than calculations. You could use this as a note-taking guide when teaching number lines and opposites. An answer key is provided for your convenience.
Using a 100s chart or a number line with a pointer, work with your class to count up to 100 by ones and tens. As a part of daily instruction, prompt your kindergartners to chant count from 1 to 30. Move on to 1 to 50, and then from 1 to 100. Highlight groups of tens and count by tens in the same fashion. This should be done daily. A number line around the room can be a visual prompter for counting together at any time. A 100s chart is also great to use, especially if it is laminated and can be colored in. Use counting for transitions. Here is an example: please meet me on the rug before I count to 30, and count with me as you walk. Great practical guidance on working toward this skill base on a class level.
Math masters are introduced to graphing inequalities on a number line. After reviewing inequality symbols, they practice representing them on a worksheet. This simple lesson serves its purpose.
Number lines are great visual tools that can be used to teach a wide range of math topics. The final video of this series models how to use number lines when solving subtraction problems using the counting up strategy. Pause the video after each example and encourage learners to share alternative solutions that involve the use of a number line. Use this resource in a unit on subtraction of large numbers and build the number sense of young mathematicians before introducing the standard subtraction algorithm.
Represent, order, and compare rational numbers in order to practice placing them on a number line. Your class will use appropriate operations, methods, and tools to compute with real numbers. Then they must explain completely and clearly what was done and why it was done.
The second of eight videos on rounding whole numbers to the nearest 10 or 100 describes how to use a number line to create benchmark numbers. A review of place value and counting by 10s starts off the lesson, followed by a discussion on how to locate numbers on the line.
Students generate differences using the number line model. Because this model highlights the measurement aspect of subtraction, it is a distinctly different representation from the models presented in lessons one and two.
Students use a number line to compare lengths. They predict the differences and figure out if they are correct. They answer puzzles involving subtraction to complete the lesson.
In this subtraction learning exercise, learners use a number line to count back in 6 problems. Students draw the part of the number line that is needed for each problem.
Students solve addition problems. In this math lesson, students use a number line to solve addition problems. Students complete a worksheet of addition problems.
First graders examine the number line as an addition strategy. In this math lesson, 1st graders create a number line and use it to help them solve addition problems.
Partners solve addition equations using counters and number lines, each counting out the number of manipulatives for an addend and then combining their quantities on a single number line to ascertain the sum. They write equations horizontally and vertically to communicate conclusions. Useful for K-3; adjust numbers so they are appropriate for your class. Excellent collaborative learning design with hands-on opportunities for tactile learners.
Second graders use a number line to understand multiples.  In this number line lesson, 2nd graders use a floor size number line and calculate problems with multiples. Students complete a worksheet with multiples.
Working in a math center or an "I finished early" work station, young mathematicians will match in sequence pre-set-up rods of unifix cubes to numbers on a number line. To help differentiate tens from ones, use different colors to represent them. This activity helps young learners practice counting for meaning and allows them to visually see that numbers get larger as they progress sequentially. Hands-on and fun!
