We have been working hard on many important math standards this quarter. This week we have spent a lot of time reviewing and I am taking some assessments for our upcoming report card. We have been playing winter themed games to practice specific skills. Both first and second grade are assessed on addition and subtraction fluency. First graders should know the addition and subtraction facts through 10 in less than 5 seconds. Second graders need to be this fast (or faster) with the facts with in 20. Further, we have started learning multiplication facts in second grade. Here are some web links to interactive games that work on fluency.

There are so many fun ways to practice developing fact fluency. Here are some awesome apps we love in class. Quick Math for $1.99, students have to write the answer on the ipad. This app increases in difficulty and includes multiplication and division. If you have older students it is excellent for them as well. Math Bingo ($1.99), in this app the children are so busy playing that they don't even realize how much math practice they are getting. For first graders, also check out Addimals (free), it goes through different addition strategies. Last, I recommend Add and Subtract within 20 ($0.99), this app works on missing numbers in equations.
First graders have been exploring the properties of addition. The students are able to make fact families when given three related numbers (2+3=5, 3+2=5, 5-2=3, 5-3=2). With the understanding of addition properties, we are able to meet some other standards as well. For example, students have to be able determine the unknown number in an addition or subtraction sentence relating to three whole numbers. This is one of first grade's most difficult standards. This week, we filled in missing numbers with these target snowmen.
The most challenging standard for second graders this quarter has been building a foundation for multiplication. Before we began learning facts, we built arrays....then we built some arrays...and last, we built some more arrays.
Next, we used are knowledge of arrays to build a multiplication table. The students really understood the reason we multiply. They made some great connections. Now we are ready to bring some facts to memory.
