Here is what we did today:

Music: Please see Ms. McMillian's blog for more detail.

Inquiry into Language: Today we worked on Spelling Lesson #2 and pgs 10-11 in their cursive workbooks.

Recess/Lunch

Inquiry into Math: Our lesson started with a review of rounding, comparing and ordering numbers. Once we said we were all confident, we did an exit ticket quiz on those concepts.

Daily 5: We did some silent reading and we fell in love with the reading corner! We all wanted to sit in there.

French: Please see Mme. Rawan's blog for more detail.

Recess/Lunch

Inquiry into Math Continued: We continued our lesson on estimating sums and differences. There was three ways that we focused on: Rounding, Clustering and Front End Estimation. When rounding to estimate a sum: look at the place value of both numbers you are rounding. Are they the same place value? (Ex. adding two 3-digit numbers means you are rounding to the nearest 100) Then round both numbers and add them together to get your estimate.

IF the numbers you are rounding are not the same place value (Ex. A 2-digit plus a 3-digit number) then you round to the tens (the lower place value). 

Front End Estimation:
We loved this way of estimation! Look at the first digit of both numbers you are adding. Then you change the remaining digits to zero.

Clustering:
When you have two numbers that are close to the same hundreds and tens when rounding you can use clustering. For example: 297 + 304 --- both individual numbers when rounded by the hundreds are 300 + 300 and when rounded to the tens are 300 + 300.

When estimating differences, we use rounding! It is the same process as rounding to estimate a sum.
