Ten Frame (NCTM Illuminations Tools) http://illuminations.nctm.org/Activity.aspx?id=3565
A nice manipulative version of the ten-frame. Probably best used by the teacher or at a learning
station because the text is quite small. Students use counters and enter a number that answers a
question. There is also a five-frame applet.
3 Hands-on Activities
Additional Activity: Number Bracelet; 10 minutes
Materials: Chenille Stem & 7 beads per person
Students thread beads on chenille stem and twist ends together to form a bracelet. Separate the
beads to make number sentences such as 4+3=7. Also flip to show that 3+4=7. Show other
addition and subtraction sentences.
Key Standards Supported
Counting And Cardinality
Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
