 * Day 5 - Manipulatives **


 * I love the manipulatives! The pattern blocks are my favourite! Although Nathan and I thought of several ways to use the linking cubes. **
 * Examples: **
 * · Ratio problems – make a shape that is ½ yellow **
 * · Integers – use the cubes like algebra tiles and let the red cubes by positive one and the blue be negative one. **
 * · Graphing translations, reflections, rotations – create a shape and reflect it **
 * · Probability (listing outcomes) – place cubes in a bag and select one and record colour **
 * · Probability – now calculate probability of selecting a specific colour **
 * · Solving equations (balancing) – place cubes into a box hidden from view (say 3 per box) place 5 boxes on one side of an equal sign and then 15 on the other and have students calculate the number of cubes in each box. **


 * I didn’t like the algebra tile application because it didn’t let you add zero pairs and then when you’re trying to represent 2 – (+5) and add the zero pairs the question will say 5 + (- 3). I would consider using the actual algebra tiles (non-virtual) so that students aren’t confused by the equation at the top automatically changing. **
