Estimation

Estimation Station: Establish a regular center in the room which changes weekly. A simple clear plastic container is filled with different items each week. These items should vary in size to challenge students' developing concept of volume, as it relates to smaller or larger units. Use seasonal items: acorns, leaves, candy corn, popcorn kernels, pumpkin seeds, etc. to spark student interest. Keep a class journal of these activities in which students may record their estimates. Record the item and the actual count along with a digital picture, if possible, of the container and the student(s) whose estimates were closest. Some classes involve parents by asking for volunteers to send in appropriate items to be counted. It is important to use the same container for several weeks so that students build an understanding that size matters in estimating how many items there are in the jar.

• Download Estimation Station Recording Sheets to use for this activity. Keep sheets in a binder to provide a growing record of student growth in estimating.
• Suggestions for using recording sheets: Have each student write his/her name and estimate on Page 2. After counting, circle or color in the student(s) whose estimates were closest. Teachers may elect to print in names at the beginning of the year and simply copy each week so that student names are always in the same location for easy checking.
• Take a picture: Use a digital camera to record the winner(s) holding the jar each week. Add the picture to page one by simply covering the estimation jar clip art.

Math-Literature Connection - Estimation: The Biggest Pumpkin Ever by Stephen Kroll would be a great literature connection for a Huge Pumpkin Estimation Station or to introduce a class pumpkin sorting activity.

• Read more about these pumpkin activities in Pumpkins, Pumpkins Everywhere.

Math-Literature Connection - Estimation: The Candy Corn Contest by Patricia Reilly Giff would be a great literature connection for a Candy Corn Estimation Station, as described in the book. The sneaky teacher in this story required that students read a page in a library book for each guess they submitted. Math teachers might vary this requirement to include some fun math practice as a way to earn guessing rights. Either way, incorporating the actual candy corn jar estimation is a great seasonal variation of the Estimation Station described above.

Coordinate Graphing

Coordinate Graphing Art: These activities require students to use coordinate pairs to correctly color in the squares of the grid to create a fall picture.

• Jack-o-Lantern: download the instructions for the Jack-o-Lantern coordinate graphing activity.
• Monster: download the instructions for the Mad Monster? coordinate graphing activity.
• Graphing Greenery challenges students to trace leaves on grid paper, then identify and list coordinate points so that classmates are able to recreate their leaves, using only the coordinates.

Coordinate Graphing Games:

• Play Grab the Candy Corn Game which requires students to toss two dice, form an ordered pair, and remove a candy from that space, if possible. The game can be played with counters or with real candy for a holiday treat that is appropriate from Halloween through Thanksgiving. The file contains the gameboard, directions, candy counters and a recording sheet.
• Catch the Spider Game: students try to catch their opponent's spiders by identifying the correct coordinate pair. If the student fails to find the spider, then he/she is caught in the web and loses his/her turn for that round. There are two 5-point spiders and ten 2-point spiders to be caught, making the game a bit more challenging as students try to capture the most points.

Probability

• Math-Literature Connection - Probability: Read There Was an Old Lady Who Swallowed a Bat by Lucille Colandro, then;
  • Enjoy the Batty Old Lady Probability activities.
  • Use Scholastic's Edible Estimation suggestion to incorporate measurement into this book talk. Scroll down the Scholastic page to locate this section.
  • After reading the book, investigate Batty Old Lady Probability, Students spin to collect all of the items the Batty Old Lady swallowed, and tally each spin on the recording sheet. They then calculate the total spins it took them to get all 7 items, and add that figure to the class data. Teachers may help students analyze the class data and learn about probability in the process. The pdf document includes directions, game mat, picture cards, spinner, recording sheet and writing to learn handout.
  • Download Old Lady template to use in retelling the story
  • After reading, enjoy the original There Was an Old Lady Who Swallowed a Fly book, enjoy the Old Lady and Probability lessons.
  • Use the Old Lady reproducible for students to design their own versions of the story.
  • Use Scholastic's Edible Estimation suggestion to incorporate measurement into this book talk. Scroll down the Scholastic page to locate this section.

Play math games to develop students' conceptual understanding of probability. Have students collect data, analyze the data, graph the data and write about their findings. Provide time for students to play games several times so that they are able to use their knowledge of probability to better control the outcome.

• Spider Game-1 develops student understanding of the probability of the outcomes of tossing a single die. This game is a twist on Pig in that tossing a 6 means the spider takes all of the counters you have been able to remove from the board. The PDF file contains the gameboard, directions and a student recording sheet.
• Spider Game-2 uses two dice to develop student understanding of how probability changes with the additional die.
• The Fat Bat Game puts a spin on the traditional game of Pig, challenging students to analyze the probability of a single die and apply their conclusions to win the game.

Ten Apples Up on Top by Theo Le Sieg

After enjoying the book, and counting the apples on the various pages, have students create counting booklets with a page for each number 1-10. They may draw that many apples on their head.

• Use Ten Apples Template to create booklets.
• Ten Apples up on Top lesson plan provides counting and stamping experience to develop the mathematical ideas in the book.

Create the fall sequel booklet, Ten Pumpkins Up on Top, in which students balance pumpkins on their heads. The pdf file contains a cover and a sample student page that may be copied so that students can draw pictures of themselves in costume, balancing 10 pumpkins. Or, create a class counting booklet with each student balancing increasing numbers of pumpkins, as assigned.

• Turkey Mat and Feathers: students use the feathers to model addition stories.
• Pumpkin Mat: students my use any manipulatives to model addition stories on the pumpkin mat.
