Plan

•
Preparation (optional):
◦ Sign up for an account on Sumdog and create accounts for your students.
Activity (60 min):
◦ Quickly review whole numbers (5 min)
◦ Play Sumdog games (25 min)
▪ Pass out the student handouts. These will explain how to use the website.
▪ Have the students start playing any game, starting at the “easy” topic listed
on the handout (“Ordering numbers up to 20”).
▪ Every 10 minutes, stop the students for a brief discussion and have them try
the next harder topic.
▪ For advanced students, encourage them to try the “challenge” topic on the
worksheet (“Ordering positive and negative numbers”).
◦ Classroom activity (30 min)
▪ Divide the students into teams and have them stand on different sides of the
room.
▪ Each student should write down a number on a piece of paper in large print
(filling the sheet). For now, they keep it to themselves.
▪ On “Go”, students show each other their numbers and the teams race to order
themselves correctly.
▪ You can repeat this, increasing the difficulty (e.g. numbers over 50).
