Tasks: Known and Unknown Facts

To help kiddos develop their fact fluency they need to start seeing relationships between the facts they know and the facts they don’t know.  This video explains a way to have your kiddos create their own set of “strategy cards” based upon their own personal Known & Unknown Facts.

Here’s a video to help you understand how to use the documents.

    Thank you for sharing your wonderful ideas about known and unknown fact cards. It is a very authentic activity i can’t wait to try out!

    Hi Christine,
    I started this activity as a revision activity for 3-D shapes, angles and lines. I asked students to make their own cards and then write down any facts they about each topic – one fact per card. After the students complete the activity so far, I was a bit hesitant to take it further because if students started to answer their partners facts then they would end up with their partners cards and not their own, which means, their collection of cards for the ‘known facts’ would not be complete or a true reflection of that they know Andrew they may feel shortchanged if ithey end up with more unknown fact than known facts.

    I hope you understand my dilemma and can advise me on how handle this situation I find it arises.

    Thank you
    Kind regards

      Sorry I didn’t see this comment before. After they find their Unknown Facts and are working with a partner, they actually give their partner their personal Unknown Facts flashcards. So for instance if John and Sue are partners, John would give Sue his set of Unknown Fact cards so she can flash them at him and practice his strategies for the facts he doesn’t know. Then Sue would hand John her set of cards to have him flash them to her to work on.

    I’m really looking for examples of how this would look like in a class with questions stem ideas.

    Helping students make connections and make sense of math is vital. Affording them the opportunity to utilize known facts builds confidence and lays a firm foundation for understanding the “Why” of the math concept.
