A Resource for Teachers A Tool for Young Children Authored by Jeffrey Frykholm Ph D This book is designed to help students develop a rich understanding of multiplication and division through a variety of problem contexts models and methods that elicit multiplicative thinking
I try to teach strategies that can be applied to any multiplication problem. I have never found success with giving my students specific strategies to use with specific math facts. Typically, if a student can remember to double and then double and then double for the 8s, they are able to actually memorize the math facts. Instead, I prefer to use mu...
This is a typical strategy that most students begin with. I like to encourage my students to add quicker (by combining) and add mentally. This strategy is a foundational one that will help the students understand the other ones. This is why this is so heavily focused on in 3rd grade. If your students are unable to do repeated addition, they may str...
This multiplication strategy is a newer one to me and I use it in a specific way. I don’t encourage my students to necessarily draw arrays. Instead, I use the visuals of different arrays to help them see the connections and known facts “inside” a more difficult fact. As you can see from this example, 4 x 4 can be decomposed visually into 2 x 4 and ...
The decomposed array strategy leads right into the next strategy. For this strategy, the students use their known facts (usually 1s, 2s, and 5s) to solve unknown facts. Here you can see that the 8 x 4 can be solved by decomposing the 8 into 5, 2 and 1 and solving (some students may do 5s and 3s). And the 6 x 7 can be decomposed into 5 x 7 and 1 x 7...
Like repeated addition, skip counting is another foundational strategy that students learn in 3rd grade. I like to expand on this by having students use their skip counting skills to solve the unknown multiplication facts that they are unable to skip count for (4s, 6s, 8s for example). As you can see from the example, students can use their skip co...
The “Add a Group” strategy is just like the name implies. The students use the multiplication fact that is one group less (and easier or a known fact) to help them derive the unknown fact. As you can see from the example in the image, students can use 5 x 6 to help solve 6 x 6 by adding another group of 6 to 30. Or they can solve 3 x 8 by adding an...
Similar to the above strategy, this strategy has the students “taking away a group”. The “Take Away a Group” strategy (in my experience) works best when solving 4s and 9s (using 5s and 10s respectively).
Hopefully this post was informative and you can use these strategies with your students. Click here to grab the printable multiplication strategies posters shown on this post.
Introduce each strategy one at a time and allow for direct targeted practice with that strategy. Students will eventually gravitate toward the strategies that work best for them (or for the particu...
A good multiplication worksheet for grade 4 will include times table problems such as 427 x 4 and 198 x 7, as an example. Students won’t start seeing 2 digit by 2 digit multiplication problems until closer to 5th grade which gives them plenty of time to master these intermediate math skills.
Now, let’s talk about those multiplication strategies. This is a typical strategy that most students begin with. I like to encourage my students to add quicker (by combining) and add mentally. This strategy is a foundational one that will help the students understand the other ones. This is why this is so heavily focused on in 3rd grade.
If your 4th and 5th graders still struggle understanding multiplication conceptually, they may struggle with these strategies as they build their understandings. The strategies are conceptual so using these will help.
However, this strategy (and the next one) do have specific multiplication facts that they work best with. The “Add a Group” strategy (in my experience) works best when solving 3s, 4s, and 6s (using 2s, 3s, and 5s respectively). Similar to the above strategy, this strategy has the students “taking away a group”.
