This week in maths we explored adding and subtracting 20's, 30's and 40's from any given number on a number chart. We reviewed place value using tens and units. The children continued exploring the concept of partitioning using 2 digit numbers (11-19) and they began looking at different strategies used when adding 2 digit numbers and single digit numbers (16+3). At the end of the week we took a break from numbers and looked at symmetry. We had fun finding the line of symmetry on letters of the alphabet and shapes. In our unit of inquiry we focused on time.
