Concept/skill: 
Fluently multiply multi-digit whole numbers using the standard algorithm.

Problem/activity:
Problem 1
Solve using the standard algorithm. If you get stuck, use an area model and/or the partial products algorithm to help. Then assess the reasonableness of your answer.
a.
$$5,803\times46$$
b.
$$63\times2,116$$
Problem 2
Dunkin' introduced a croissant doughnut in 2014. In the first three months of its debut, they sold 7,870 dozen of them per day. How many croissant doughnuts were sold in the first three months?


Answer: 
Yes. This set of problems involves multi-digit whole numbers because the numbers in each problem are four and two digit integers, and the mathematical calculations involved in both problems focus on multiplication. The first problem explicitly asks the student to solve its subproblems using the standard algorithm.

Now, assess whether the following problem or activity is 'aligned' with the given Common Core standard in Mathematics.

standard_description: Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
problem_activity: Narrative
The purpose of this activity is for students to learn stage 2 of the Target Numbers center. Students start with 25, choose a number card and decide whether to add that number of tens or ones. Students play six rounds and the student who gets as close to 95 as possible without going over is the winner.
MLR8 Discussion Supports.
Prior to playing the game, invite students to make sense of the directions and take turns sharing their understanding with their partner. Listen for and clarify any questions about the directions.

Number cards 0–10

Target Numbers Stage 2 Recording Sheet
Launch
Groups of 2
Give each group a set of number cards, two recording sheets, and access to connecting cubes in towers of 10 and singles.
“Take out all of the cards that show 0 or 10.”
“We are going to learn a new way to play Target Numbers. This time, your goal is to get as close to 95 as you can, without going over. You only get 6 turns. On each turn, you get to decide whether you want to add tens or ones to your number. Let’s play a round together. Each partner starts at 25.”
Demonstrate drawing a number card.
“I drew a [4]. Should I add 4 ones or 4 tens? Why?” (You can add 4 tens because that will give you 65. You still have 5 rounds to get to 95. You can add 4 ones to make 29. That gives you more time to add tens.)
30 seconds: quiet think time
30 seconds: partner discussion
Share responses.
“I’m going to add 4 tens, 2 tens and 4 tens is 6 tens. So my sum is 65.”
“Once my partner and I agree on the sum, the partner who drew the number card records an equation. Since 25 is already filled in for me, I will record the number as tens (or ones) and the sum.”
Demonstrate completing the equation.
“After I write my equation, the sum becomes my starting number for the next round, so I write it in as the first number in the next equation.”
If needed, play another round with the class.
“Take turns drawing the number card, finding the sum and writing an equation. Each player plays 6 rounds. Whoever gets closest to 95 without going over is the winner.”
Activity
10 minutes: partner work time
Activity Synthesis
“When you draw the number card, what is your method for deciding whether to add that many tens or ones?” (I think about how close I am to 95. That helps me think about whether to add ones or tens.)
