Handwriting
We brainstormed words with a "bossy e" or a "silent e" that make the other vowel say its name in words such as:
cave --> long a
Pete --> long e
ride --> long i
cove --> long o
cute --> long u
We wrote one word for each vowel three times and the date once.

Math
We explored strategies for estimating the answer when subtracting two digit numbers.
For example:

68 - 23 = ?

1) Round to the nearest 10.

68 --> 70
23 --> 20 70 - 20 = 50 So 50 would be your estimate.

2) Just look at the tens.

68 has 6 tens
23 has 2 tens 6 - 2 = 4 So 4 tens or 40 would be your estimate.

3) Leave the top number alone and round off the bottom number.

68 --> 68
23 --> 20 68 - 20 = 48 So 48 would be your estimate.

We started to work on page 108 making sure to only use estimates and to show how we estimated.

Science
We watched a Brain Pop on the Earth's structure. We learned that the Earth has three main layers: the crust, the mantle, and the core.
We wrote notes about each layer and did the Brain Pop quiz.

Fine Arts
We finished our Olympic Rings collage from yesterday.

No School tomorrow as it is a Professional Development day for staff members.
