Big Ideas: 10 groups of 100 can be combined to make a "thousand." This lesson has students apply what they know about ones, tens, and hundreds to create 4-digit numbers. Students will start by thinking about what 1,000 means and move to creating 2 groups that add up to the given 4-digit number. Students are expected to come to the understanding that 10 groups of 100 make 1,000 (as they did in previous lessons when exploring 10 groups of 10). This exploration is a foundation for adding and subtracting within one thousand and working with numbers all the way into the millions. Special Materials: Base ten blocks
