for Frog Day
students will complete addition and subtraction problems
using a number line.
- Individual number lines
(1-10 or 1-20, depending on the grade level) for each
student or each pair of students. (There are
number lines printed on the bottom of the
worksheets.) Or as an alternative, make a large
number line on the classroom floor and have the
students be the frogs to "hop" out the math
- A "frog marker"
for each student (or pair). Use the Frog
Marker Graphics to print and cut out the frogs.
Hopping Worksheet (1-10), or Frog
Hopping Worksheet (1-20).
- If available, read the
book "Ready, Set, Hop" (Mathstart Series) by
Stuart J. Murphy. It's a good lesson on hopping
to answer addition and subtraction problems.
- Pass out the number lines
- Work as a class to discuss
how to use a number line to figure addition and
subtraction problems. Practice as a group. If
you have made a number line on the floor, have the
students take turns hopping out some sample problems.
- Pass out the worksheets
and have the students complete them individually, or
as a class, depending on the age level.
- For older students, have
them use the number lines to complete algebra
problems. For example, "If a frog is on the
number 2, how many hops must he take to get to the
number 5?". You may want to introduce the
equation 2 + x = 5.
- Have the students make up
story problems that involve frogs.
- Have the students measure
how far they can hop.
