We continue to explore important concepts within the Number Sense & Numeration strand of the math program. Knowing the friendly numbers for 10 helps children to build their understanding of number relationships. For example, if we know that 1+9 = 10 (1 and 9 are a friendly number set for 10) then it can help us to more easily calculate what 9+2 is (1 more than 10). We continue to practice skip counting by 2's, 5's and 10's using tools such as 100's charts, loose parts, etc., We are learning to use number lines, 100's charts and rulers as tools to help us count up and solve simple addition questions.
We have also started exploring concepts within the strands of Data Management & Probability as well as Geometry & Spatial Sense. In Data Management we are learning how to collect data by asking simple survey questions such as 'What is your favourite winter activity?' Students are learning how to tally the answers of their classmates (i.e. 1 tally mark = 1 response, circle groups of 5). They are also learning how to properly graph the information on prepared graph templates. In Geometry and Spacial Sense we are exploring 2-D shapes. Students are learning to describe and sort common 2-D shapes (i.e. square, circle, rectangle, triangle, etc .) by their attributes (i.e. number of sides, corners, straight or curvy lines, etc.).
The snowball took 4 hours to melt completely. We noticed it changed from a solid to a liquid.
Then we read:
