Learning Shapes: Triangles

Floor Shapes:  We taped triangles up and down our kitchen floor.  I got the first few started and then J helped me by decided if the triangle should be big or little and making sure I completed the triangle’s three sides.  I repeated again and again that triangles have three sides and we counted as I placed each side down.   This is my winter/rainy day version of sidewalk chalk.  If you read my sidewalk chalk post, you’ll know that I like to have something out as a consistent reminder of our weekly lessons.  Painter’s tape works well when we can’t get outside!

When the triangles were all completed, we traced them with our fingers, we walked and “jumped” across the triangle path, we drove cars around the sides of the triangles and we filled each triangle with one of his Matchbox cars (a good reminder for the number one).

Triangle Building Shapes – This is a simple activity and so easy to prepare.  All I had to do was cut out a handful of foam triangles in different sizes and colors.  I showed J how to lay the triangles next to each other to create pictures and designs (basically build with triangles instead of blocks).  He mostly wanted to match the triangles (same size and color) which was perfectly fine with me.  The point was to give him lots of visual reminders of a triangle and that was accomplished.  You could do this activity with felt or even construction paper (and glue the shapes onto paper).  I saw something similar in a learning store, but the shapes were magnetic.  I loved that idea, but I was too cheap to buy them and didn’t have time to make them!

Stickers in Triangles – I gave J a piece of paper filled with triangles and had him place one sticker inside each triangle. 

Age Attempted: 23 months (have done similar activities much younger… 18 months??)

Teachable Moments:  inside/outside (with stickers and cars inside triangle); focus on triangles having 3 sides and 3 corners/points; what shapes can we create by placing triangles together?? (foam pieces)

Try Again? I resuse these activities often
