Primary Math Activities
Short vs. Tall
Intro to Measurement
Short vs. Tall
Objective: to allow students to
compare the attributes of integer bars.
Manipulative Activity: a follow-up
activity where individual children or pairs of children compare the
attributes of the integer bars and learn the accompanying vocabulary.
Distribute integer (Cuisenaire) rods to all the children in the class.
Ask each child or pair of children to respond with a model as an
example for each of the following:
Technology Activity: Students use an
bar applet written by Jacobo Bulaevsky to reinforce concepts of tall
vs. short, horizontal vs. vertical, color, and size.
- short vs. tall
- horizontal vs. vertical
- one of each color
- a different example of two rods that have the same color
(realization that they will always be the same length if they are
the same color)
Refer to How to Use the Integer Bar Program for directions.
Depending on the availability of computers for your students, this
activity can be done individually, with partners, in groups, or as a class.
Work through the manipulative activity using the applet instead of the
Have students go to Short vs. Tall.
Paper/Pencil Activity: Depending on
the level of your students, you can have them complete this activity
individually or with assistance. Here are some possible activities:
- Students draw two bars, labeling one short and the other tall.
- Students draw two bars, labeling one vertical and the other horizontal.
- Students draw all of the bars, from shortest to tallest.
