L.E.Q. How can I use math drawings to solve and prove my answer?
What do students need to learn to be able to answer the Essential Question?
Assessment Prompt #1: How do I represent ones, tens and hundreds in different ways? H&R p93
Assessment Prompt #2: How can I draw a 3-digit number greater than 100? (Writing Prompt Intervention Activity
Card 11-1 “Explain how to write and draw the greatest and smallest three-digit number.”)
Assessment Prompt #3: How can I tell the difference between hundreds, tens and ones and place them in correct order?
H&R p 223
Assessment Prompt #4: How do I count (read, write, and draw) numbers by ones and tens over a hundred? ? (Writing
Prompt Intervention Activity Card 11-3 Write the missing numbers and explain how you knew which number to write
using a proof drawing)
Assessment Prompt #5: How can I add numbers with 1, 2 and 3 digits using secret code cards and proof drawings?
Activating Strategy
A book, such as “Earth Day Hooray” (Stuart J. Murphy) – read and allow Ss to share what they know about place value
(great way to introduce multi-digit addition)
