1. Topic-
 Number and Operations Space Systems
2. Content-
 Multiplying and Dividing Decimals to Thousandths- Common Core: "Perform operations with multi-digit whole numbers and with decimals to hundredths." Stars' Distance Relative to the Sun- NGSS: "Space Systems: Stars and the Solar System."
3. Goals: Aims/Outcomes-
 1.Students will have developed a deeper understanding of how to multiply and divide decimals. 2.Students will have developed a deeper understanding of the solar systems stars' distance relative to the sun.
4. Objectives-
 1.Students will be able to work collaboratively with a partner. 2.Students will be able to visit each planet in a mature and responsible manner. 3.Students will be able to complete the problems efficiently on their white boards.
5. Materials and Aids-
 Mini white boards, markers, worksheets, planet clue cards
6. Procedures/Methods-

A. Introduction-

 1.Explain to students that they will be multiplying and dividing decimals while working through an activity that is also related to what they've been learning in science: the stars' distance relative to the sun.

B. Development-

 1.Review the solar system stars' distance relative to the sun. 2.Review multiplying and dividing decimals. 3.Explain that for the activity, there would be a solar system for multiplying decimals and a solar system for dividing decimals. 4.Explain that there are planets taped around the room and that for the activity, the students have to visit each planet and complete either the multiplication or division problem that are written on the planet. 5.Explain that since there are two solar systems, there would be two of the same planets taped around the room; one planet for multiplying and the other planet for dividing. 6. Pass out the worksheet and describe to the students how one side is for multiplying and that the other side is for dividing. 6.Read through the directions and explain to the students that they will visit each of the planets and work out the problem using mini white boards. 7.Explain to the students that they would place their answer in the box (on their worksheet) next to the picture that represented the planet that they visited.

C. Practice-

 1.Students will be grouped into pairs and will begin to visit each planet and therefore, complete the multiplication and division problems. 2.Teacher will walk around the room, making sure the students are on track. The teacher will answer any questions the students might have.

D. Independent Practice-

 1.The teacher will observe the students working on the problems to make sure they are completing the problems correctly.

E. Accommodations (Differentiated Instruction)-

 1.Students all had the same worksheet. It was expected of the students that they would work together and help one another.

F. Checking for understanding-

 1.Teacher will review students' answers on the worksheet to determine whether they were able to answer the problems correctly.

G. Closure-

 1.The activity will end, students will pass in their worksheet, and the teacher will ask students what skills they practiced during the activity. 2.The teacher can also ask whether they learned anything new/whether they enjoyed the activity and why.
7. Evaluation-
 Teacher will review the students' worksheets and develop a score for each one.
8. Teacher Reflection-
 The students were eager to start the activity and they all seemed to enjoy visiting each planet. All of the students worked collaboratively with one another. The majority of the students were able to complete the problems correctly. Only a couple of the students were having some difficulties when dividing decimals. All of the students seemed to be able to multiply decimals with little to no problems. The answers on the worksheet reflect that the students have developed a true understanding of how to multiply and divide decimals. However, the errors on the worksheets were mostly related to the division problems so the students might need a more direct explanation of how to divide decimals.
