2nd Graders learning multiplication? Oh yes today they learned their first multiplication facts which by the picture at the top of this post was, guess what? Multiplying by 10! The students worked in pairs today using the unifix cubes (in groups of 10) to find multiples of 10. If a pair of students had 3 groups of 10 unifix cubes, they would come up to the board and write 3 groups of 10 as well as 3 x 10 =30. Then I would have the groups give away certain groups of 10 to other student pairs and they would find how many groups of 10 they had after the switch. The students did a really wonderful job with their groups of 10 and even found the trick/pattern to multiplying by 10, which is to take the original number and add a zero to it. I have posted some links to 10’s multiplication to the bottom of this post.
The students then had the chance to work on subtracting two-digit numbers with regrouping as I took 3 students at a time to work in a small group while the others worked on reading and math. A few more students were able to understand and do the regrouping with no help from me so I am very proud with the progress the second graders have made over this week in math.
In reading the students just worked on their activity packet. Together we went over possessive nouns as well as pronouns and how to use them in a sentence. The students are in for a treat next week as we move from Unit 4: Animals into Unit 5 which deals with biographies. This also goes along with what the students have been learning in English which is biographies of George Washington and Abraham Lincoln. The first week in February the students will be working in pairs on a biography project in which they read a short biography of their given person then they will create a timeline and picture book about their person and present it to the class. So we are coming up to the end of the week again and so far the students have made a lot of progress, especially in math, this week and I am so excited to see them be excited about learning!
