Coin-Rubbing Matching Game

In this lesson, children will examine the attributes of coins to identify similarities and differences.

Math Lesson for:

Toddlers/Preschoolers
(See Step 5: Adapt lesson for toddlers or preschoolers.)

Content Area:

Algebra
Data Analysis and Probability
Numbers and Operations

Learning Goals:

This lesson will help toddlers and preschoolers meet the following educational standards:

• Understand numbers, ways of representing numbers, relationships among numbers and number systems
• Understand patterns, relations and functions
• Formulate questions that can be addressed with data and collect and display relevant data to answer these questions

Learning Targets:

After this lesson, toddlers and preschoolers should be more proficient at:

• Counting with understanding and recognizing “how many” in sets of objects
• Connecting number words and numerals to the quantities that they represent, using various physical models and representations
• Sorting, classifying and ordering objects by size, number and other properties
• Recognizing, describing and extending patterns (such as sequences of sounds and shapes or simple numeric patterns) and translating from one representation to another
• Sorting and classifying objects according to their attributes and organizing data about the objects

Coin-Rubbing Matching Game

Lesson plan for toddlers/preschoolers

Step 1: Gather materials.

• Colored pencils or crayons (colored pencils work better than crayons because kids find it difficult to NOT push hard while coloring. Gentle shading is difficult to practice. That is why colored pencils are a perfect solution, since the pressure exerted does not affect the coin impression as much.)
• A variety of coins (pennies, nickels, dimes and quarters)
• Paper (larger newsprint paper works well for this project)

Note: Small parts pose a choking hazard and are not appropriate for children age five or under. Be sure to choose lesson materials that meet safety requirements.

Step 2: Introduce activity.

1. While showing coins (quarter, nickel, dime and penny), ask the children if they know the names of the coins that you hold up.
2. Describe the attributes of each of the coins (the quarter is bigger, the dime is the smallest, the penny is a different color, etc.)
3. Explain that, today, they will be exploring coins further by doing rubbings of the coins and creating patterns with the coins.

Step 3: Engage children in lesson activities.

1. Give each child a few coins, sheets of white paper and crayons or colored pencils. Ask them to lay out a few coins on a sheet of paper and cover the coins with another sheet of paper. Then make coin impressions by coloring over the coins with the colored pencils.
2. Ask the children to match the coins with their impressions.
3. Make an attributes chart. Ask the children to look for and talk about the similarities and differences between each of the coins. You  can help by clarifying the attributes that the children are noticing by identifying the various presidents and landmarks on each of the coins. You can also connect the coins with the equivalent number amount.

• Lay out a few coins on the paper, cover them up with another sheet of paper, ask the children to do crayon rubs and guess what coins are underneath the sheet of paper, then ask them to check their guesses by doing new coin rubs.
• Create coin rubbings and math/money equations.
• Create a pattern with the coins and then instruct the children to rub and create designs. Have the children create their own patterns.
• If you end up using crayons, wash over the paper with watercolors so that the crayon colors will pop out. You could do the coin rubbings with a white crayon and create a “secret” money activity sheet. The children can then use watercolors to reveal the coins.

Step 4: Math vocabulary.

• Equal to: To be the same in number or amount (e.g., “A dime is equal to 10 cents.”)
• Similarities: Having like attributes (e.g., “What similarities do you notice between these two coins?”)
• Differences: Not similar in size, shape, color or other characteristic (e.g., “What differences do you notice between these two coins?”)
• Quarter: A coin worth 25 cents (e.g., a quarter of a dollar)
• Dime: A coin worth 10 cents (e.g., tenth of a dollar)
• Nickel: A coin worth five cents (e.g., fifth of a dollar)
• Penny: A coin worth one cent

Step 5: Adapt lesson for toddlers or preschoolers.

Toddlers may:
• Need help understanding the connection between the coin rubbing and the actual coin
• Need help attaching a coin name to the appropriate coin
Home child care providers may:
• Point out similarities and differences between the coins (help the children to notice the different coin sizes and the pictures on each of the coins and then connect those attributes to the same coin to complete the matching of the coins)
• Further extend the activity so that the children are using the coins in a variety of different ways (create a pattern with the coins that the children can rub to create designs or ask the children to create their own patterns)
• Reinforce the names of the coins as the children are matching up the coins with the rubbings (make a list of each coin’s various attributes, e.g., Quarter: largest coin, eagle soaring on one side, George Washington on the other side)
Preschoolers may:
• Easily identify the various attributes of the coins
Home child care providers may:
• Introduce the number equivalences of each coin
• Create coin rubbings or math/money equations practice sheets or games
• Provide games that further solidify their knowledge (lay out a few coins on a sheet of paper, cover them up with another sheet of paper, ask the children to do crayon rubs and guess what coins are underneath the sheet of paper, then ask them to check their guesses by doing new coin rubs)

Outdoor Connections

Set up a general store. Some of the children can be merchants and the others can be buyers. Use only the coins used in the rubbing activity (quarters, dimes, nickels and pennies). Tell the merchants to price their items. You can bring some items from the classroom outside or sell found objects such as rocks or pinecones. The prices should be in keeping with the coins (5 cents, 25 cents) so that the children won’t need to figure out how to make change. The merchants can write up price tags or the buyers can simply ask the price of each item. Once the children have played for a while, tell the merchants and buyers to switch roles.
