Students will understand that numbers that have the same value can be represented in different ways. The suggested public discussion of student work shows connected solution paths for three-digit place value. It is important to discuss this work together because students in Grade 2 are asked to deal with larger numbers with more digits. Three pieces of work are shown. The first shows a student who understands base ten by drawing the base ten short hand. In this example, the student clearly can count each separate place value. In the second example, the student models the understanding of place value by using a number sentence rather than drawing the base ten pieces. In this example, the student represents the scoops with a number rather than a drawing. In the third example, the student combines both the drawing of base ten pieces and representing the base ten with a number. This student models the base ten shorthand and gives each of the hundreds, tens, and ones a value showing an expanded form of the number with grouping. This Student Work Discussion Plan was created by a member of the 2015 Delaware Dream Team. Special Materials: Base Ten Blocks, Base Ten Placemat
