This 13 page packet includes everything from basic number bonds to ten up to adding to the thousands place. It is meant to teach basic number sense and mental math as well as addition with carrying. Includes scaffolded worksheets to help everyone be successful. This packet is based on Singapore methods for teaching addition by using number bonds and expanded addition. Addresses 3.NBT.2 but could also be used for 2.NBT.5 (not using the sheet with thousands or using those for advanced kiddos) or as a building block for 2.OA.2.
