Strategies for Multiplying by Multiples of 10

Math

One of the skills we cover in second grade (which I know is often a third grade skill) is multiplying by multiples of 10. This can off scare kids as you are using larger numbers, but I knew my kids could handle it. To make it a little less scary, I introduced it using a story problem. I put the problem below up on the board and read over it with the kids.

Then, I told the kids to solve it on their white boards at their seats. I didn’t give any prompting or suggestions, I wanted to see what they would come up with on their own.  Boy was I pleasantly surprised! They had amazing strategies! As you’ll see below they came up with multiple different ways to come to the answer.  They all understood it was equal groups and they used strategies we had talked about with multiplication – drawing out equal groups, skip counting, repeated addition, breaking apart numbers, etc. I was so proud of them. After giving them time to solve I had students bring their white board up to explain their strategies to the class.

This honestly was the best way I have ever introduced it. Instead of me telling them how to figure it out or only showing them the trick (8 x 3 = 24 so 8 x 30 = 240), they really took them time to try to figure it out for themselves. And it helped because on future problems they knew multiple strategies they could use to solve it.

Test Prep Review Ideas

Math, Reading

It’s getting to be that time again….the dreading testing season is about to begin! I know April and May can be quite chaotic for teachers with all of the end of the year activities, but it is also chaotic with all of the testing!  We test in early May so April tends to be a lot of review. And, while reviewing can be boring, I’ve done a few things the last year or two to spice it up a bit.

Reviewing content is important throughout the year, but refreshers are always good as testing approaches. Last year I wanted to freshen things up a bit and try to make reviewing as fun as possible.  One way I did this was by changing up the way we reviewed each day.  For example, in math, we reviewed different skill areas each day. One day we worked on place value, one day operations, one day patterns, etc.  To keep it fresh, we reviewed these skills in different ways. This way no two days was the same. And – it helped! The students enjoyed reviewing more and were more engaged (which is the whole point of this :-)!)

Here are some ideas for how to review math skills…these can be applied to different grade levels and skills:

  • Egg Hunt – Yes, I know Easter is over, but an egg hunt is fun for everyone. To practice our operations skills (addition, subtraction, multiplication, and division) I created an egg hunt for my kids.  They were able to go around the room hunting for eggs and then they had to solve the problems inside the egg on the recording sheet. They loved it!  I also differentiated by putting more difficult problems in certain colored eggs and more on-level problems in others. This way I was able to challenge the kids who were ready.

  • Match-Up – Another activity I did was a match-up activity with partners. Students had the multiplication or division problem and had to match the problem with the answer card.

  • Around the Room – Kids need to move and they especially need to move as we get closer and closer to the end of the year. Last year I created an Around the Room activity to review place value. It included expanded form, place value model, comparing numbers, and writing numbers in standard form.  Kids were up and moving and able to review the different place value skills we worked on. You can find Place Value Review – Around the Room in my TPT Store…here.  I also created an Around the Room activity to review the pattern skills that we did a different day to avoid repetitious review activitie

  • White Board Review – Another skill we reviewed was understanding story problems. Our standards include being able to solve story problems, but also being able to identify the operation and the number sentence that matches. I put a PowerPoint together and the kids would respond to the question on their white boards and then we’d do a quick show and discussion.

   

  • Kids Sharing Out – This was an idea I saw on Instagram last year and I wish I could remember where because it is genius!  I put different operation and story problems on larger poster paper around the room. Students then went around and solved the problems on their own recording sheet.  Once they finished that, I partnered the kids up and gave each partnership one of the hanging poster boards.  They had to solve that problem on the chart paper. Then, they had to get up and present to the class how they solved it.  Great way to practice math communication and review!

   

 

    

I know many of these ideas are focused around math, but you could still use the same review activities, but with reading or ELA skills. I will also be doing language arts and reading review with lots of task cards.  For reading – I also highly recommend looking at ReadWorks. They have tons of multiple choice passages like the students will see on many of these standardized test.
