Invitation to Learn
Today students will become "doctors" of numbers. They will "operate" on numbers and take them apart to better understand how they
work.
Instructional Procedures
Begin by passing out envelopes of Place Value Tents.
Have students write the patterns and connections they found during the activity in their journal. Also have them explain how to add or subtract 100 from their number.
Read Anno's Magic Seeds by Mitsumasa Anno. Have the students use their journal and Place Value Tents to make the numbers. Make predictions for the next page or number of seeds Jack grows. Have students show the number on their cards, write the expanded notation and prediction for the next number.
Students will learn to double their number and subtract one. Ask how many seeds Jack will have in 30 years? 50 years? See if the students come up with a pattern.
