Math Lesson
for Frog Day

 Objective: The students will complete addition and subtraction problems using a number line. Materials 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 problems. A "frog marker" for each student (or pair).  Use the Frog Marker Graphics to print and cut out the frogs. Frog 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. 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.
