# Carnival Candy Challenge: Connected Solution Paths

Students will understand that a 2-digit number is composed of tens and ones and can be decomposed into tens ones in multiple ways. This task requires students to use their knowledge of place value to decompose a number. Students will use a visual representation to match the quantity 26 and to represent it 3 different ways using place value drawings. The suggested public discussion of student work shows solution paths that are connected through the values of different place value pieces and equations. Students may notice that a group with 2 tens and 6 ones is the same as 1 ten and 16 ones. The number 26 can also be represented through addition and multiplication equations and still represent place value. Three pieces of work are shown, beginning with a response that uses two visual representations of 26. This is followed by work that uses three representations of the number 26. The third piece of work shows four different equations that represents the number 26. This Student Work Discussion Plan was created by a member of the 2015 Delaware Dream Team. Special Materials: The following materials are suggestions: Place value mat, place value materials such as "10 sticks" and bits (ones)
