Kindergarten - 1st Grade
Counting Collections
Materials:
- A variety of different objects
- Buckets/containers to hold objects
- Paper
- Pencils
- Crayons/markers/colored pencils
Preparation:
Organize the materials into different containers and take note of how many objects are in each container. For consistency, try and group the same or similar objects in the same containers.
Purpose: Children will be able to count the amount of items in each container and write down that amount. Then, children will be able to compare and contrast the amounts in the containers and create an image to show their findings.
Possible Interaction:
Adult: I have X amount of containers with different amounts of objects in each container. I need your help figuring out how many objects are in each container. Your job is to count each object and write down the number of objects in each container. You can write down the number on a piece of paper so that we can remember it later.
Child: Counts objects in each container and writes down the amount in each container.
Adult: Now that you're done, you're going to tell me how many objects were in each container.
Child: Reads off how many objects were in each container. (Note: if the child has not stated the correct number for a bucket, that is okay. You can ask them to recount and try again, or move on to the next portion of the activity.)
Adult: Great job! I want to be able to quickly see how many objects were in each container, so I think that we should create a picture to show how many items were in each. (Older children can create a graph if desired, but drawing a picture with the correct amount of items in each container is sufficient. Children can be creative and represent their findings in whichever way they feel most comfortable!)
Child: Creates image.
Adult: (Possible questions) Which container had the most items? Which had the least? How many more items did this container have than that container? Did this container have more or less items than that container?
Standards:

Is it Equal?
Materials:
- Materials to count (coins, beans, pieces of paper, etc.)
- Piece of paper with an equals sign in the middle
- Small piece of paper with an addition sign (optional)
- Small piece of paper with a subtraction sign (optional)
Preparation:
Split the paper in half down the middle by folding/drawing a line and draw an equals sign in the center. The child should have enough room to place on amount of something on one side and another amount of something on the other side. Gather counting materials.
Purpose:
Children will demonstrate their knowledge of the equals sign and what it means for two things to be equal/the same. Children can practice counting skills and compare/contrast two amounts or numbers.
Possible Interaction:
Adult: Tell me what you know about the word "equal."
Child: Shares their knowledge.
Adult: We're going to be seeing if these two different groups of items are equal or not. The adult places a certain amount of items on one side of the paper and either the same or different amount of items on the other side of the paper. Are these two sides equal?
Child: Counts the items on both sides and determines whether or not the sides are equal or not.
Adult: Continues process with other numbers and amounts. If child is confident in addition and/or subtraction, the adult can place one amount of counters on one side of the paper (i.e., 8) and one amount of counters on the other side separated by either the addition or subtraction sign (i.e., 5 + 3) The child can decide whether or not the sides are equal based on the operations. The child can also create their own number sentences using the materials available.

Finding Fractions
Materials:
- Paper
- Ruler
- Scissors
Purpose:
Introduce children to fractions and offer a review of how fractions can make up a whole.
Preparation:
On various pieces of paper, use a ruler to (or equally fold) mark various portions of the paper. This could be one mark, right in the middle of the paper or eight equal marks. One you have decided how many portions you will make out of the piece of paper, that determines what your denominator will be.
Possible Interactions:
Adult: *holding full piece of paper* How many pieces of paper do I have?
Child: One
Adult: *cuts piece of paper along the marks made previously* How many do I have now?
Child: X amount of pieces of paper
Adult: *holds up a few of the pieces, but not all* How many do I have now?
Child: X amount of pieces of paper
Adult: So I have X out of Y pieces of paper?
Child: Yes, you have X/Y of a piece of paper in your hand.
Adult: How many more pieces of paper do I need to make the paper whole again?
Tips:
Using many different pieces of paper with different numbers of cuts will help your child work with different fractions and amounts. For more of a challenge, you can ask your students more questions, such as: Can you simply that fraction? What would that number look like on paper? How do you know it is only X/Y amounts of paper?

Preparation:
Group together various household items of your choosing. Try to keep similar items together or keep sizes relatively the same. Encourage your child to group the items into sets of two until they have 0 or 1 left over. If they do not have any left over, there is an even amount of items. If they have one left over, there is an odd number of items.
Possible Interaction:

Child: Hmmmm.
Adult: How about you group them in sets or two.
Child: *separates items into sets of two*
