Example:
Concept/skill: 
Represent addition and subtraction with objects, fingers, mental images, drawings (Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

Problem/activity:
Task
Materials
One 10-frame per pair of students (see example below)
[IMG]
Counters, 10 per pair of students
Decks of number cards 0-5 (with 4 of each number) or two 0-5 dice
Setup
This activity is done in pairs. The students sit side by side with 10-frame and deck of cards or dice. If they have cards, the cards are shuffled and placed face down in front of them.
Action
Player 1 flips a card or rolls the die. They place that many counters on the 10-frame. Player 2 flips a card or rolls the die. They place that many more counters on the 10-frame next to the counters already on the ten frame. The students count the total together.
A recording sheet can be added when the students have been introduced to equations and number sentences. For those students who can handle higher numbers, a deck of 0-10 cards and two 10-frames can be used.
This game can also be played alone.


Answer: 
Yes. This task involves representing addition with objects such as number cards and dice.

Now, determine whether the following problem or activity can enable students to understand the concepts or skills in the provided description.

K
standard_description: Apply properties of operations as strategies to add and subtract. (Students need not use formal terms for these properties.) Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
problem_activity: Narrative
This optional activity allows students to practice adding tenths and hundredths (and to reinforce their ability to compare fractions) through a game. Students use fraction cards to play a game in groups of 2, 3, or 4. To win the game is to draw pairs of cards with the greater (or greatest) sum, as many times as possible.
Consider arranging students in groups of 2 for the first game or two (so that students would need to compare only 2 sums at a time), and arranging groups of 3 or 4 for subsequent games. Before students begin playing, ask them to keep track of and record pairs of fractions that they find challenging to add.
Required Materials
Materials to Copy
Fraction Action: Tenths, Hundredths
Required Preparation
Create a set of cards from the blackline master for each group of 2.
Launch
Groups of 2 for the first game or two, then groups of 3–4 for subsequent games, if time permits
Give each group one set of fraction cards from the blackline master.
Tell students that they will play one or more games of Fraction Action.
Demonstrate how to play the game. Invite a student to be your opponent in the demonstration game.
Read the rules as a class and clarify any questions students might have.
Activity
“Play one game with your partner.”
“As you play, you may come across one or more pairs of fractions whose sums are hard to find. Record those fractions. Be prepared to explain how you eventually figured out which sum is greater.”
“If you finish before time is up, play another game with the same partner, or play a game with the players from another group.”
15 minutes: group play time
Student Facing
Play Fraction Action with 2 players:
Shuffle the cards from your teacher. Place the cards in a stack, face down.
Each player turns 2 cards over and adds the fractions on the cards.
Compare the sums. The player with the greater sum wins that round and keeps all four cards.
If the sums are equivalent, each player turns one more card over and adds the value to their sum. The player with the greater new sum keeps all cards.
The player with the most cards wins the game.
Play Fraction Action with 3 or 4 players:
The player with the greatest sum of fractions wins the round.
If 2 or more players have the greatest sum, those players turn two more cards over and find their sum. The player with the greatest sum keeps all the cards.
Record any pair of fractions whose sum is challenging to find here.

Activity Synthesis
Invite groups to share some of the challenging expressions they recorded and how they eventually determined the sums.
As one group shares, ask others if they have other ideas about how the fractions could be added.
