Question 3. Every day, Penelope jogs three laps around the playground to keep in shape. The playground is rectangular with a width of 163 m and a length of 320 m. a. Find the total amount of meters in one lap. Answer: The total amount of meters in one lap is 52,160 square meters,

Explanation: Given the playground is rectangular with a width of 163 m and a length of 320 m So the total area of the playground is 163 m X 320 m = 52,160 square meters. Therefore the total amount of meters in one lap is 52,160 square meters Penelope jogs.

b. Determine how many meters Penelope jogs in three laps. Answer: Penelope jogs 1,56,480 square meters in three laps,

Explanation: Given every day, Penelope jogs three laps around the playground to keep in shape. The playground is rectangular with a width of 163 m and a length of 320 m so total area of the rectangular playground is 163 m X 320 m = 52,160 square meters Now for 3 laps it is 3 X 52,160 sq mt = 1,56,480 square meters.

How to Multiply in Columns with Regrouping

Once students have learned to multiply in columns with no carrying, they move onto multiplying in columns with carrying. This means that the sum of the multiplying numbers is larger than 10, or 100, or 1000, etc., so the resulting 10, 100, 0r 1000 is moved to the column to the left.

Multiplying with regrouping is best explained in an illustrated example.

Multiplication with carrying

Let’s use this example: 718 x 6

That will look like this in columns:

When you multiply in columns, you start by multiplying the ones. Like this:

The 8 goes in the ones column and the 4 goes in the tens column, like this:

Now let’s move onto multiplying the tens column by 6. Don’t forget to add the 4 tens.

See how the 1 hundred moved up to above the 7 hundreds?

Now, let’s multiply the hundreds column with the 6. Don’t forget the add the 1 at the top.

The answer is: 718 x 6 = 4,308

Essential Question

Unlock the Problem

By 1914, Henry Ford had streamlined his assembly line to make a Model T Ford car in 93 minutes. how many minutes did it take to make 25 Model Ts? Answer: 2,3 25 Estimate: 2,700 Explanation: By using place values and regrouping to find the estimate.

Use place value and regrouping.

Mathematical Processes Explain why you will get the same answer whether you multiply 93 × 25 or 25 × 93. Answer: It shows the Commutative Property. Explanation: Commutative property :  The order of the factors does not change the product. A x B = B x A Let’s look at an example of the commutative property: The result of multiplying 93 x 25 will be equal to multiplying 25 x 93. Although we change the order of the factors, the result is still 2325 .

Different Ways to Multiply You can use different ways to multiply and still get the correct answer. Shawn and Patty both solved 67 × 40 correctly, but they used different ways.

Question 1. What method did Shawn use to solve the problem? Answer: Area models help to multiply large numbers, in a simpler form using a multiplication box. Explanation: Show the problem as the area of a rectangle, and then break that rectangle into smaller chunks for easier solving. This method is also known as box multiplication. Next, multiply to find the area of each smaller rectangle.

Texas Go Math Grade 4 Answer Key Lesson 8.5 Question 2. What method did Patty use to solve the problem? Answer: She used place values and regrouping methods. Explanation: We can multiply 2-digit numbers by multiplying and by finding each partial product such as the tens and ones separately, then add all partial products together.

Share and Show

Mathematical Processes Explain why you can omit zeros of the first partial product when you multiply 20 × 34. Answer: Multiply 34 and 20 to get 680 Add the partial products. 0 + 680 = 680 Explanation: As zero has no value and when we multiply any number with zero the product is zero.

Estimate. Then find the product.

Problem Solving

Practice: Copy and Solve Estimate. Then find the product.
