Patterns on a 100 chart
Our quest to learn more about patterns continued yesterday as we explored patterns using a 100 chart! We began by adding two more terms to our list of mathematical vocabulary: pattern rule (e.g. start at 3 and add 3 each time) and skip count (1, 3, 5, 7...). We practiced using pattern rules on our 100 chart together as a class by projecting a large 100 chart on our white board and using markers to shade in the boxes to create our pattern. We noticed that when you shade in boxes on a 100 chart, it also creates different colour patterns such as: 4 white boxes, 1 coloured box, 4 white boxes, 1 coloured box.
We also learned about a function on our calculator which allows us to skip count in another way! When we enter in 3 + 3 = 6 into our calculators and then repeatedly press the = button, we are skip counting! This is a great way for students to check their work when it is complete.
Some students even began to create their own pattern rules with a 100 chart and challenged other classmates to solve them!
