Building a Garden � You have 36 yards of fencing for your vegetable garden. If you want to make a rectangular garden that has side lengths that are whole yards long what are the possible dimensions of your garden? � Which garden gives you the most space? � What if we had 48 yards of fencing?

Technology Options… � Area Explorer � Spreadsheet

Related concept � Perimeter � Real-life Explorer link context?

Making Connections � Area and Perimeter ◦ Where in the SOLs? � Area/Perimeter� When 3. 10, 3. 11, 5. 8 (a, b) we work on area and perimeter what other concepts are we working on? � What process skills or practices are students developing?

Algebraic Thinking � Pan Balance � Choose Set 6 � Task- Find the values of the various shapes.

Pan Balance � Real-life context? � Cereal boxes now come in different shaped boxes. Miniwheats come in a square box and cost $1. Use the balance to find the price of Bran flakes (circular box), Tangerine Charms (Triangular box), and Organic Mix (Kite shaped box).

Pan Balance � Numbers � How not shapes would this be used “effectively” by students?

Fractions � Ordering and comparing fractions

Fraction Pointer � What with? concepts or skills are students working

Fractions �A game…. Fraction track

Fraction Track � What concepts and skills?

Thinking Blocks � Singapore � Models Math with objects online

Templates � Thinking Blocks � Base 10 blocks � Geoboards � Pattern Blocks � Cuisenaire rods

Games and Other Resources � Let’s go!

A few thoughts… � Technology for drill and practice and repetitive practice Vs. � Technology to support problem solving and higher-order thinking � Billions of dollars spent on putting technology in students’ hands…how are we being responsible stewards of that technology?
