This one is made of dense red foam, has a white surface that can be used with dry erase markers, shows numbers 1-50 and has 2 channels running the length of the number line. Your base tens slide right into the channels. Includes an 8 pg activity guide. Use to demonstrate addition, subtraction, multiplication and division. Measures 20.5” x 4” x 5” ~ Sara

    This was a little different than I was expecting. A strip of laminated posterboard (4 1/8" x 19.5") marked with a linear "clock," i.e. hours from 12 am to 12 am with five minute designations and fifteen minutes labels to help you calculate elapsed time. There is also space to write a start and end time digitally and on an analog clock face with additional space to show the elapsed time digitally.

The color alternates between red and white every 10 partitions/divisions. Includes magnets for hanging. Works with quality dry erase markers. ~ Deanne

    I love it when you can add to a product and get more mileage out of it. If you are using Unifix cubes as a math manipulative with your child, you can take it a step further using this number line set. These are 12 pieces of plastic panels with the numbers 1 through 120 (each piece has an increment of ten) across the top, #1-10 across the bottom (so you can count full tens and extra ones) and a channel between the two into which you insert the linked cubes. The panels alternate between gray and ivory making it very obvious where the tens start and stop. They interlock like a race track, end to end. Ridges and raised numbers across the bottom are a sensory delight for a kinesthetic learner, and the bold black numbers at the top are flat but stand out visually. A (very) small activity guide is included. Practice counting, place value, operations and fractions! Cubes are sold separately. ~ Sara

       This unique flip book offers a visual way to teach fractions to your student. 18 pages of write-on/wipe-off number lines can be used to help your student understand. Represented on the number lines are thirds, quarters, fifths, eighths, tenths, twelfths, sixteenths, percents, and decimals. Open the book horizontally (pages are 4” high and 12” wide), the top page is a blank number line with just marks for the correct placement, and the bottom page is a number line with fractions printed in the correct location. For example, thirds have a blank number line with four markings, the number line that is marked shows 0, 1/3, 2/3, and 1. The write-on/wipe-off page allows the student to practice writing the correct placement for fractions. There are no blank number lines for decimals and percents; students can see the correlation between the two because they are side-by-side. There are three blank number lines at the back of the flip book, no markings of any kind, so that students can practice writing fractions.
