Please see this post for a wonderful math problem Ms. Storey's math class took on this week!
This problem involves addition up to 20. Being able to think about a number as made up of different "parts" is so important to number sense. Practicing not just 2 addend problems (8 + 12 = 20), but also multi-addend problems (5 + 3 + 6 + 6 = 20) helps introduce students to multiplication, and helps them with "fast facts". You can create other open-ended math questions with contexts! For example, there are 100 marbles in a bag, in the colours red, blue, green, and white. Jane draws 10 marbles out of the bag. How many of each colour might she have drawn? How many different combinations are there? Create your own problem and leave it in the comments below!
