Three Dimensional Pop Out Shapes

I like the kids to do "busy work) while we do our read alouds.  Sometimes they can come up with their own thing - finger knitting, drawing, colouring, bracelet making, a puzzle, etc.  But sometimes I give them an activity to do too.  The other day I had Victoria and Austin do these three dimensional pop out shapes.  I got the idea from here.  They drew them with pencil first and then traced the lines with a black sharpie marker.  The colouring in was done with oil pastels.  I love how they turned out.  

Victoria's is the blue one and Austin's is the red one.
