Curriculum Connection: "In pre-Kindergarten through Grade 2, all students use multiple models to develop initial understandings of place value and the base-ten number system." Principles and Standards for School Mathematics, National Council of Teachers of Mathematics Lesson Plan (Grades 1-2): Use the game of Digotto to give students practice with place value. Discuss the "places" -- ones, tens and hundreds. Go through some examples on the chalkboard. Organize the students in groups. Ask each group to make a chart with three columns: • Hundreds • Tens • Ones Now, have them use the chart while playing a round of Digotto. Ask the team to write the rule at the top of their chart. When each DigitDroid comes out of the machine, show the team how to "try" the number in different columns.
The team should work together to evaluate each number, based on the rule. They should ask questions like:
Understanding the way place value relates to the number's value will help the students beat Teemto at his own game. |
