Here are some helpful videos to learning the skills in sections 3.8 and 3.9 in our current math chapter.
Keep practicing you doubles, doubles plus one and doubles minus one, and changing the order of addends. :)
I just wanted to inform you a little bit about my grading policy. I am sure you are seeing different worksheets with a star, smiley face, or a check mark. Each symbol means something different. I wanted to share with you how I grade seatwork assignments.
In class we have been working hard memorizing our doubles facts. It is important that you also practice this skill at home. This way when we are doing doubles plus one and doubles minus one your child will understand the new material better. The first step is knowing the doubles. I would recommend writing doubles on the front of an index card and the answer one the back. For example, 1 + 1 on the front and the answer on the back. Quiz your child every night and they will be very successful in the skill. Practice doubles all the way up to 10 + 10.
