Kindergarten is just completing Unit 4 of the Math program. They are busy with numbers 0-10. A child is said to have concrete knowledge of numbers up to their age. Observe your child counting a large number of objects. It is common to see a child recognize the correct number of objects, 0-5, without needing to count, but when there are more objects, 6-10+, children will skip objects and/or count objects more than once. A child may recognize the number 8, but not really know how many 8 is the way we as adults can quickly recognize 8 of something by breaking 8 down to 4 and 4, etc.
Therefore, in Kindergarten many activities are used to break down the numbers so the children can have more concrete knowledge. This concrete knowledge is actually the beginning of addition and subtraction. They have been completing 10 frames every tenth day since the start of school. During morning bin time, the children have been building 10 frames. One Math time activity involved counting the dots on dominoes and sorting them. The next Unit covers numbers up to 31 and the fun will continue!
