Math Monday: Danish Hearts

A seemingly simple woven ornament, popular for children in Danish kindergartens, famous at IKEA around the holiday season, proved to be a serious challenge for Monday Math!

The first attempt, was a simple paper weave practice.
Not too tricky. Ms. C could manage with help, chanting a pattern of "over...under...over...under"

The pocket weave requires two tone 3x9" fabric rectangles with rounded ends.
Fold in half lengthwise and make several lengthwise snips on the fold.
Think hands without thumbs.
The pattern of weaving now changes from "over...under" to "inside...outside"
Ms. O and I both needed help!

By the third attempt, we learned it actually makes a pocket (when done correctly)!
Brilliant design!
