Answer:The purpose of this task is to support students' reasoning based on place value to multiply a single digit number by a multiple of 10. This reasoning builds on and supports knowledge described in 2.NBT.A.1, 3.OA.A.1, and 3.OA.B.5. If used in an instructional setting, students might benefit from having access to base-ten blocks. Students should also be encouraged to use a number line marked with tens. An empty number line is an excellent tool that helps students who are ready to develop a more abstract understanding of place value but are not yet ready for a purely symbolic solution approach.
