Five more days to go!!!!
But who's counting? In our classroom, I think it is everyone. Reminder - Monday is pizza day. Reminder - Wednesday is the Holiday Celebration concert, 1:40 in the afternoon, and 7pm in the evening. Speaking of counting, we are doing quite a lot of it these days. Today, we explored a few mental math strategies to use when subtracting. Students copied down two useful ones today in their notebooks. Here are some sites for practice: This one demonstrates a few strategies at the top. http://www.aaamath.com/sub28c-submm.html http://www.amblesideprimary.com/ambleweb/mentalmaths/subtractiontest.html http://nlvm.usu.edu/en/nav/frames_asid_155_g_2_t_1.html Here's one we had before, this time choose "Inverse Operations" http://www.primaryresources.co.uk/online/bricks2.swf This one looks familiar, it is the one where you repair the slide - only this time with subtraction. http://www.bbc.co.uk/schools/ks2bitesize/maths/number/subtraction/play.shtml Finally, here are a couple of quizzes: Grade Four http://www.nelson.com/nelson/school/elementary/mathK8/math4/quizzes/math4quizzes/m4ch4l5.htm Grade Three http://www.nelson.com/nelson/school/elementary/mathK8/math3/quizzes/math3quizzes/m3ch4l5.htm Hmmm, that should keep us busy for the weekend. Speaking of which, have a good one!
