Title: Who is the Greatest?
Description:
Students will gain more conceptual understanding of comparing 3digit numbers. They will build numbers using base ten blocks and a hundreds chart and work with a partner to decide which number is greater. They will be making decisions about which place value to put the digits in to construct the greatest number.
This is a College and CareerReady Standards showcase lesson plan.
Standard(s): [MA2013] (2) 5: Understand that the three digits of a threedigit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases: [2NBT1] [MA2013] (2) 8: Compare two threedigit numbers based on meanings of the hundreds, tens, and ones digits using >, =, and < symbols to record the results of comparisons. [2NBT4]
