The Importance of 10 - Math Coach's Corner

The Importance of 10

Written by Donna Boucher

Donna has been a teacher, math instructional coach, interventionist, and curriculum coordinator. A frequent speaker at state and national conferences, she shares her love for math with a worldwide audience through her website, Math Coach’s Corner. Donna is also the co-author of Guided Math Workshop.

Yesterday, I posted about effective fact practice. Developing automaticity with addition and subtraction facts begins with subitizing, which is why it’s so important that our Kinder babies get a lot of practice with that skill. The next building block is knowing combinations for 5 and 10. If a student has instant recall of 3 + 7, it sets the stage for knowing 4 + 7. That’s the idea behind teaching facts with a strategy-based approach. Here’s a quick and easy little workstation using ordinary playing cards (remove the face cards) to practice combinations for 10. Notice that by using the playing cards and ten-frames, it is a representational (from CRA) activity, which is better for conceptual understanding than abstract flash cards.

    This great! Thank you! I know you focus on k-5 but do you have any resources as far as manipulatively for sixth grade concepts?

      Christine, many of the same manipulatives used for upper elementary work well for sixth graders. I also wanted to share this blog post on middle school manipulatives.

    I taught 2nd grade for 5 years. So many started 2nd with me not fluid with 10! This will help me get these Kinders on the right road.

    Thanks!

      I taught FIFTH grade and many still were not fluent with 10! So much more emphasis on number sense I think now.

    Love this!! Any chance that you’ll create a second version where you turn over two cards, color that number with one color, and use another color to complete the two ten-frames? This would be a good fit for my higher math students.

    LOL! We actually have names for each friend. 1,9 straight backs,
    2,8 curvy heads,
    3,7 swingers and when we write it on the board we hang the 7 off the 3,
    4 and 6 connectors… We make a 4 and go straight into a 6,
    5,5 twins
    0,10 the zero heroes
    Kids love the names and love drawing them, and it’s amazing how something so simple helps them remember this skill!!!!
