We've built some flexibility into this resource so it can be used in a variety of ways. There are also options for use where the classroom technology is limited.

Here are some of the ways to use it:

• As a complete homework activity: The 38 Challenge was originally made for home use and you can see the home version here. To use it as a homework you'll need to direct learners (and parents) to komodomath.com/38  Here are some printable homework task slips you can distribute. It may be a good idea to introduce it as a whole class activity before using it as a homework.
• As a whole class activity: The 38 Challenge is suitable to use as a whole class activity. Step 1 ( the video) and Step 2 ( the practice grid) work well on an interactive whiteboard. Step 3 ( the quiz ) is best used at home as a certificate and feedback is emailed privately to parents on completion. The whole class activity can be enhanced with the printable worksheets for steps 1 and 2 - see the teacher notes below.
• As an individual learner classroom activity: If you have access to a suite of tablets or laptops you can use the 38 Challenge in small groups or individually. The practice grid exercise can be repeated without refreshing the page. Step 3 ( the quiz ) is best used at home as a certificate is emailed to parents on completion.

Thanks for using the 38 Challenge! Feedback is always welcome! If you'd like to be in the loop for more please join our teacher club. 

This short one minute video demonstrates that when you remove the easy tables and the matching commutative facts, you're left with only 38 tables to learn. This makes learning tables feel so much more achievable. The video streams from vimeo.com. Since some schools block vimeo, you can download the video in advance. Here is a captioned version.

The video conveys a lot of information pretty quickly, so it might be an idea to develop this into a whole class interactive whiteboard activity by using this full complete times tables grid or this blank grid. You can follow the video's dialogue step-by-step, striking off rows and columns on the grid as you go.

The interactive practice grid can be used individually or as a whole class activity on an interactive whiteboard. Completing the 38 in under 4 minutes is a good indication of fluency, however, this will depend on how quickly the learner can input the answers on their device. Note that the practice grid delivers all commutative tables options randomly - so you'll see 7 x 8 and 8 x 7 appearing in the same square randomly.

If this can't be used individually in the classroom these printable options may be useful:

• 38-challenge-homework-slips.pdf - to direct pupils to the web page at home
• Blank times tables grid (with the 38 challenge squares highlighted)
• Completed 38 Challenge grid
• Completed 12x tables grid

The 38 Challenge quiz is a multiple choice quiz that measures how accurately and quickly the 38 times tables are answered. It's designed as a homework task and is fun and engaging - please give it a run through to see. At the end of the quiz, all learners receive a certificate - here's a sneak peek and an accuracy and fluency report  - as seen here.

At the start of the quiz, we ask for a parent's email address so we can send both the report and certificate to them. Parent and learner contact information is kept private and they can opt out at any time.
