In math the children are learning an important strategy. Use what you know, to help figure out what you do not know. At this time, the doubles addition facts are almost automatic for most children. They can use these facts to solve more difficult addition problems. For example, if you know that 5+5=10, then 5+6 must be one more than 10. In a similar vein, if you know that 5+5=10, then 5+3 must be two less than ten. The children have looked at base ten frames and the arrangement of dots on a die to practice this skill. They are also practicing explaining this strategy in words, using a the phrases, “ If I know ______, then I also know_______.” Playing games with this concept as you drive with your child, will be helpful additional practice!
