Description

  • Students work in pairs and take turn selecting an equation card.Β  Each student uses the skeleton hands and individual bones to represent one of the numbers in the equation.Β  Ex: 6 is made with one skeleton hand (5) and one bone (1).Β  9 is made with one skeleton hand (5) and four bones (4).
  • CREATING A HIGH FIVE:Β  Once both addends are represented, players can combine hands to make 10.Β 
  • FINDING THE SUM:Β  Count on from 10 (made by the 2 hands) to include all of the individual bones.Β  Ex: 6+7= 10(2 hands) + 3 (3 bones) = 13.Β Β 
  • DIFFERENTIATION: Some students may be able to trade 5 bones for a skeleton hand before adding all to find the sum.Β 
  • OPTIONAL:Β  Students who are ready for more of a challenge can use the worksheet to record their answers.Β

to see state-specific standards (only available in the US).
Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
Apply properties of operations as strategies to add and subtract. If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
