Review A Lesson Plan

MAFS.5.NBT.2.5

Fluently multiply multi-digit whole numbers using the standard algorithm (DOK1)

· Creating an EXCEL spreadsheet that categorizes types of multiplication and division problems based on product unknown, group size unknown and group number unknown.

· Fluently multiply multi-digit whole numbers (not to exceed 5 digits by 2 digits) using the standard algorithm

· Find whole number quotients of whole numbers with up to 4 digit dividends and 2 digit divisors, using strategies based on place value, the properties of operations, and or the relationship between multiplication and division. Illustrate and explain the calculations by using equations, rectangular arrays, and/or area models.

· Multiply multi digit whole numbers (not to exceed 5 digits by 2 digits) using a variety of strategies.

· Find whole number quotients of whole numbers with up to 4 digit dividends and 1 digit divisors using a variety of strategies.

· Multiply 5 digit whole numbers by 1 digit whole numbers

· Find whole number quotients of whole numbers with up to 3 digit dividends and 1 digit divisors, using a variety of strategies.

ENGAGEMENT :

3 statements are written about multiplication.

2 of them are true & 1 is not true (fiction).

Stand up when you hear the “fiction” statement

Example:

1. You always start with the ones digit and multiply across the top.

2. The numbers you multiply are called the product.

3. The numbers you multiply are called the factors.

Now you try! On your note card write 3 statements about multiplication.

Remember…2 must be true and 1 must be fiction.

CRITICAL INFO: Having students color code the place value and then change color when moving on to the next digit can help. Walk students through how this is done by also using the steps within the traffic light on the slide. Students need to use standard algorithm for each problem. The stop light will be used throughout the lessons on multiplication, but today we are only focusing on the green light.

Traffic Light: when explaining the traffic light to students –

1. GREEN – (Multiply the top) means to multiply the digit in the ones place (green) by each of the digits in the top number.

2. YELLOW (drop it like it’s hot and multiply the top) means to add in the place holder and the multiply tens digit (yellow) by each of the digits in the top number.

3. RED (ADD (+) and show ‘em what you got) means to add up the green and the yellow products to get your final answer.

Today we are going to 
learn a new way to chat 
with our partners. Let’s learn how to play 
”Carousel Feedback“ (we will be using this method throughout the week so students get comfortable with it.)

Directions: Give students a minute or so to solve problem #1 independently. At the end of the minute they will pass trade papers with their shoulder partner. Each partner will write 2 comments on the paper they now have in 30 seconds. One comment should be something that they did well and the other should be something that they could do better. At the end of 30 seconds they will give papers back and repeat with #2.

INDEPENDENT:

1. Provide the independent questions to students

2. Students should not have to spend time copying the questions

3. List all independent questions on one slide

Check for understanding: Based on your checks for understanding – students may work in pairs or in a teacher-led small group to complete the independent practice problems

Answers:

1. 24 x 14 = 336

2. 145 x 21 = 3,045

3. 17 x 38 = 646

4. 653 x 45 = 29,385

Table top activity

1) Give each group a copy of table top twitter slide

2) Students will each have a different colored crayon

3) Set a timer and students will write what they know about multiplying decimals

4) If a student agrees with what another student wrote they can put a smiley face & comment on what each other writes

5) Share out some of the thoughts
