The beads are in groups of fives to support subitizing. General Information: A Rekenrekis made of two rods, each containing ten beads. Teacher Information Rekenreks: Flexibility with 9 Corresponding Number Talks are on slides 11-13. How did knowing the amount of dots from the first ten frame help you find the amount on this ten frame?.How many more would you need to make ten?.How many boxes are on a ten frame? How many are empty? How many are full?.How are the dots arranged on the ten frame?.Could you find how many dots there are without counting them one by one?.These skills are the foundation to computational fluency with addition and subtraction. General Information: Ten frames can be used to show decompositions of quantities, build fluency, subitize, and develop and understanding of conservation (a quantity can be represented in more than one way). Teacher Information Ten Frames: Flexibility with 10 Corresponding Number Talks are on slides 7-9. This Number Talk occurred during the second quarter of school. uses dot images to facilitate a Number Talk in Kindergarten. This Number Talk occurred during the first quarter of school. uses ten frames to facilitate a Number Talk in First Grade. Number Talks In Action Curious to see a Number Talk in action?

Scattered Dots Five/Ten Frames Rekenreks* *A Rekenrekcontains two wires. Students determine the amount, and make connections to the previous image since they are typically related. Steps 1-4 are repeated for the remaining problems.The teacher records so thinking is visible to all students. A few students share answers and thinking.Students find the total quantity of dots on the first image.The teacher selects a Number Talk slide, and reveals the first image for three seconds.Through frequent experiences, they begin to rely on perceptual subitizing (instantly seeing the amount), conceptual subitizing (seeing parts within the set, and using mental processes to find the total quantity), and known number facts. At first, kindergarten students may rely solely on counting all dots to find the quantity. The image is briefly displayed for three seconds, encouraging students to use strategies other than counting all to find the total quantity. Kindergarten students work with these quick images to find “how many”. Later in the school year, they focus around expressions.
During much of Kindergarten, Number Talks utilize dot images, ten frames, and Rekenreks.How Do Number Talks Look in Kindergarten?.Numbers are organized into groups of ones, tens, hundreds, etc.What we know about small numbers can help us work with large numbers.What we know about one number can help us work with other numbers.Numbers can be decomposed and combined with other numbers in a variety of ways.Numbers are composed of smaller numbers.Through frequent Number Talks, students will recognize:.This supports the development of early fluency skills. Through regular opportunities to work with dot images and expressions, students develop an understanding of number relationships and structure. A Number Talk is a brief routine (about 10 minutes) focused around developing flexibility and fluency with numbers.Kindergarten Number Talks Fourth Quarter Adapted from Number Talks: Helping Children Build Mental Math and Computation Strategies, by Sherry Parrish Number Talks Teacher’s Guide, Cumberland County Schools
