|
| |
|
2. Content-
|
Use Math 180 M book and computer lesson to make use of structure
and construct viable arguments for answers
VOCAB estimate, factor,partial product and place value |
| |
|
3. Goals: Aims/Outcomes-
|
| Students will decompose the 3 digit factor when multiplying 1 digit
by 3 digit problems |
| |
|
|
4. Objectives-
|
1.Apply distributive property when multiplying 1 digit by 3 digit
factors
2.Apply place value understanding to estimate and compare products
|
| |
|
5. Materials and Aids-
|
| Math 180 book, computer, white boards |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
1.Students solve a problem with multiple solutions and analyze the
relationship among the numbers to identify a pattern
2 DO NOW ticket mbook pg 68
|
| |
|
|
B. Development-
1.Revisit last lesson and model how to split a 3 digit factor
2. Discuss strategy used to split rectangles (COMPUTER)
3. Play instructional video
4. Model making an estimate and discuss what it means
5.Use distributive property to rename a 3 digit factor and find partial
products
6.Add partial products and model reasonable answers |
| |
|
|
C. Practice-
IN M Book, guide students through:
1.ESTIMATE the product
2.Rename the 3 digit factor
3.Find partial products
4.Add partial products
5. Solve problems in pairs |
| |
|
|
D. Independent Practice-
1.Assign remainder of problems
2.Teacher checks after the 1st
3.Student finishes and then transitions to use skills on computer
activity |
| |
|
|
E. Accommodations (Differentiated Instruction)-
After teacher check, if students are still having problems understanding,
pull to small group and reteach
|
| |
|
|
F. Checking for understanding-
Complete exit ticket and hand in
|
| |
|
|
G. Closure-
Revisit estimation and talk about when you might use it in real
life.
