Are you looking for a performance task to challenge your students? Looking for a purposeful real-world task to engage your learners? This birthday party performance task guides students through the process of calculating an expense plan for a typical birthday party. I created it for my fourth grade enrichment group, but it could easily be used with fifth graders as well. The standards I chose to target were 4.OA.3, 4.NBT.4, and 4.NBT.5.
