Give students problems to solve, but don’t tell them to find the answer. Tell them to name a fact that can help them solve the problem, instead. Have students explain aloud how a related fact helped them solve a problem. For example, 5 + 6 = 5 + 5 + 1 (5 doubled is 10 and one more is 11) Teach the commutative property.

- The Origins of “Hundred” Did you know that the word “hundred” actually means 120, not 100? Its roots can be traced back to the old Norse term “hundrath.”
- The Birthday Paradox. In a room with just 23 people, there is a 50% chance that two of them share the same birthday. This may seem counterintuitive, but the probability of a shared birthday increases rapidly as the number of people in the room grows.
- The Evolution of Mathematical Symbols. Most of the symbols we use in mathematics today were not invented until the 16th century. Before that, equations were often written in words, which made mathematical expressions more cumbersome and difficult to work with.
- The Alphabetical Order of “Forty” “Forty” is the only number in the English language that is spelled with letters arranged in alphabetical order. This unique linguistic quirk adds an interesting twist to the number's representation and makes it stand out among its numerical counterparts.
Multiplying by 9 and 7. Related math facts are also helpful when multiplying by 9 and 7. To multiply by 9, multiply the other factor by 10 and then subtract one group of that factor. So if solving 7 x 9, multiply 7 by 10 to get 70 and then subtract 7 to get 63. You may also be familiar with the 9’s hand trick.

It’s essential that students are learning their strategies before trying to memorize the facts. Strategies such as doubles, doubles +1 and +2, make a ten, adding 1, adding 2, adding 0, etc. are all strategies that, once learned, help students to add their facts more quickly.

It sounds complicated but it’s not. Subitizing is being able to glance quickly at a set of objects and recognize it as a number. When students are able to subtilize they no longer have to use one to one correspondence to count out and add objects. Groups of objects for subitizing can come in many forms: ten frames, fingers, dice, dominoes, base ten...
Simple. Grab a deck of cards. Lay down two numbers. Add them together. Nothing fancy and yet still effective. If you want to add variety do doubles, making ten, addition/subtraction war, double digit, or even add three numbers.
“Students love Kahoot. This game can be played one on one or as a team. Electronic devices such as iPads, phones, or computers are needed. Players see the displayed math fact, solve, and provide answer on their device. The correct answer is displayed on Kahoot after the timer expires (or once all students have submitted their answers). The quicker ...
If you are a teacher, don’t place ALL the responsibility on yourself when it comes to getting students to master their math facts. Send these ideas home for parents to try with their child(ren). Make it fun. Add a challenge spin to it. Get them involved.

When students have a math notebook, they have a portfolio of math practice and learning that they can refer back to. These are also great for parent teacher conferences. I especially love using math notebooks for students to reflect and write about their learning. When a student has to provide a written explanation of how they solved a math problem...
Lay out a “timed test” sheet on each desk. The students do as many as they can until the music stops then they rotate to the next sheet. It gives the slower students a sense of accomplishment since it’s “everyone’s” paper not just theirs but there is a lower stress level even though they are doing it as fast as they can.
Moby Maxis a website for students to practice their math facts. The primary reason that Moby Math is so effective is because students do not waste time practicing material they have already mastered. Instead, Moby targets areas where students are struggling and allows students to progress immediately once mastery is achieved. There is a free trial ...
certain number of new facts in a given day. Learning new facts is a process that occurs over time, and trying to “cram” a large number of new facts into memory in a few days just doesn’t work. When planning for Reflex, keep in mind that shorter, more frequent sessions will be more effective than longer, less frequent sessions.
