Patterns on the Hundreds Chart

In Math, we have been working on Subtracting 2 digit and 3 digit numbers.  As the students feel more confident in subtraction, throughout the year, we will be working more with subtracting 3 digit numbers.  The students have been using many strategies to solve a variety of subtraction questions. We have also been looking at the vocabulary in subtraction word problems to see what words tell us that we need to subtract e.g., difference, take away, how many more, fewer, etc. Subtraction continues to be a challenging concept for many children especially as we move towards larger numbers.  This would be an area to reinforce at home should you be looking for extension activities for homework time.  At school we will be continuing to look at these foundational math skills throughout the year.

We have started a new unit in Patterning.  The students are looking for number patterns on the Hundreds Chart and learning how to write Pattern Rules e.g. Start at 2 and add 2 each time (Pattern: 2,4,6,8,10).  We are also using words to describe number patterns such as, increasing (growing), decreasing (shrinking) and repeating.  Students have been extending patterns using a pattern core and then writing the pattern rule to describe the pattern.

We have been discovering all sorts of interesting number patterns on our classroom Hundreds Charts and having fun trying to solve each others' number patterns using just the pattern rule.
