Modeling Larger Numbers

In math we are working on modeling, ordering, and comparing numbers to 99. In this lesson the students worked in partners to build larger numbers with Base Ten Blocks. They then checked on another's work. After both partners agreed the models were correct, they represented their numbers on paper by drawing sticks (tens) and dots (ones). They then identified in writing the number of tens and ones, the expanded form, the standard form, and the written form of the numbers. They then again worked with their partners to check the work.  After checking, they discussed which number was the greatest and which was the least. They had to justify their thinking by explaining how many tens and ones were in their numbers. The partners then switched numbers with another set of partners and repeated the process.
