Week of: 10/7—10/11

2. Math Agenda Math Warm-Up Check homework Review Area Model

Take away the rectangle and use Place
Value to solve multi-digit multiplication
problems

3. Math Warm Up Draw an Area Model for the following two problems: 56 x 3
6 x 3 = 18 3
50 X 3 = 150
Add Partial Products
8 x 4 = 32 4
70 X 4 = 280

4. Today’s Lesson: Two-digit by One-digit Multiplication

5. We have learned how to multiply…
Using base ten pieces
Ex/ 24 x 3
Using rectangles
Ex/ 24 x 3
6 tens & 9 ones
= 69
20 x 3 = 60
4 x 3 = 12 3 60
+ 12 72

6. THINK! Is there a way to use place value without having to draw the rectangle?
24 x 3
24 has 2 tens (20) + 4 ones
If I multiply by PLACE VALUE:
20 x 3 = 60
4 x 3 = 12 72 4
20 x 3 = 60
4 x 3 = 12 3 +

7. Let’s Make a Connection…
When we multiply by PLACE VALUE, which form are we writing the numbers in?
34 x 6
34 =
We are writing the number 34 in expanded form
6 = 6
Can we expand the number 6 anymore? Why or why not?

8. What if we take Away the Rectangle?
Let’s look at this example….
34 x 6
Expand the two digit number
X 6 = 180
4 X 6 = 24
204 +

9. Let’s Practice This New Method Together…
45 x 8
34 x 9

10. More Practice Do the following problems with your math partner
68 x x 4
74 x x 9
34 x x 2
12 x x 3
If you finish early, more practice: p
