Welcome 5th graders,
Yesterday I was only able to see D block....so all the other groups will feel like it's been forever since we worked together in math. For instance...I haven't seen E block since Friday....wow!
If you remember, we were working on how to use the distributive property and our mental math skills to solve more challenging problems. For example...
45 x 21 can be solved by (45 x 20 ) + (45 x 1)
45 x 19 can be solved by (45 x 20 ) - (45 x 1)
Notice how we were able to mentally compute both by knowing how to double 45 (and place a zero) then either add or subtract one group of 45!
