Two Poems I Wrote to Reinforce Vocabulary Words for
Addition & Subtraction
Addition & Subtraction
Materials
 items from nature (leaves, sticks, acorns, pinecones, rocks, gumballs, seed pods, etc.)
 individual white boards/markers
 eraser for white board (Old socks work well.)
 Number cards 010
 Addition Worksheet (optional)
Addition Activity
 Read one of the books and the poems to reinforce subtraction and addition.
 The book We're Going on a Picnic is a cute book to introduce the idea of adding and taking away items.
 Have a specific number of nature items for each child to use. If you are working on combinations that equal 10, then each child will have 10 items.
 Have a stack of number cards 010 face down in the middle of a table or blanket. Children take turns flipping over the top card.
 When the number is revealed, the child puts that number of items onto his/her white board for the first number in the equation.
 He/She writes the numeral under the group of items, then a + sign. /then he/she counts the number of items that are left in the pile that will be used for the second number in the equation.
 The child ads the items on the board, writes the number below and then adds the = sign and the answer.
 After completing many of these, hopefully the children will start seeing patterns. For example if you are working on sums to 8, the child will start to recognize when they count out 4 for the first number, there will always be 4 left on the board.
Other Options
 Instead of having a stack of number cards, the children explore the different combinations of numbers that equal the designated amount. They "build" the math problems using the nature items as a visual. They keep track of their math equations on a worksheet.
 For kids who like competition, make it a gamelike situation. The kids compete against one another on who can find the most combinations using the nature items in a specific amount of time. The goal for this version is to have the kids learn new combinations in each round that they can add to the previous combinations they had in previous rounds.
 Depending on the skill level, have different amounts of nature items for the children. I a child as mastered the math facts of 10, then he/she gets 11 items and works on the combinations for that sum.
 Change the equations to having a missing addend.
 Instead of having just nature items and number cards, have story problems on cards in a pile that the students flip over, read, and then solve.
Subtraction Activity
This activity is similar to the addition activity with a slight difference.
 Using the same materials, the children have the TOTAL AMOUNT of items already written on the whiteboard. So it is the first number of the equation.
 The child flips over the number card.
 He/She writes that number as the second number in the equation.
 Then he/she takes away that amount of items from the pile to help him/her compute the answer.
 The nature items help the children VISUALIZE the math equations.
Other Options
 Depending on the skill level, have different amounts of items for each child. If a child has mastered the math facts of 10, then he/she gets a more challenging number of items to use for subtraction facts.
 Change the equations to having a missing addend.
 Have story problem cards for the child to read and solve.
