Our mental math strategy today was making magic tens. There are a few ways to make magic tens. Use the strategy that you find the easiest, but challenge yourself to use more than one strategy. For example:
38 + 45 = ?
If we use the "give and take" method, we add 2 to 38 and take 2 away from 45 so our new question is: 40 + 43 = ? It's easy to add on from ten, 40 + 40 + 3 = 83
If you had the question 67 + 23= ? you could solve it using the "give and take" method or you could see a magic ten in the ones place. 7+3 = 10 and 60 + 20 = 80 so the answer is 80 + 10 = 90.
Try these strategies for the questions below:
29 + 36
52 + 28
37 + 37
Today we also discussed different ways to represents numbers. Using 26 812...
Standard Form: 26 812
Expanded form numbers (numerals) : 20 000 + 6000 + 800 + 10 + 2
Expanded from words (and numbers): 2 ten thousands + 6 thousands + 8 hundreds + 1 ten + 2 ones

Please play the game after you finish your homework.
Literacy
Today we shared the story "Dictionary Dave" and practiced check for understanding. Remember when you check for understanding you do NOT retell the story, you summarize or pick out the most important idea or ideas.
Practice reading your book fluency out loud. Check for understanding as your read. Make sure yo know how to read all the words. Tomorrow you will be reading your book with your group. You will have a short quiz (multiple choice) after your group is finished reading. You may use the book to answer the questions.
PLEASE RETURN THE BOOK. YOU WILL NOT HAVE A BOOK TO READ IF YOU LEAVE IT AT HOME!
Science
On this beautiful day we went to explore the habitats around our school. You should have listed the living and non-living parts of area you chose to explore. If it is living, it is either a plant or animal. Thursday we will be looking at the photographs and notes you took on each area.
We saw lots of these in the tall grass. Can you identify them?
Kagan / Collaborative Work
Share with a parent the name you chose for your group. Explain how the name was chosen. It might take me a few days to learning all the creative names!
Reminders:
- Outstanding forms / $10 for Agenda
- Back to School BBQ tomorrow (Wednesday 4:30 - 6:00 pm)
