Math
Lesson
for Frog Day
Objective:
The
students will complete addition and subtraction problems
using a number line.

Materials
 Individual number lines
(110 or 120, 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
problems.
 A "frog marker"
for each student (or pair). Use the Frog
Marker Graphics to print and cut out the frogs.
 Frog
Hopping Worksheet (110), or Frog
Hopping Worksheet (120).
 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.

Procedure
 Pass out the number lines
and markers.
 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.

Other
Lesson Ideas
 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.
