# 30 Day Challenge

## IF / THEN

If we use number talks routines (i.e., count around the circle, choral counting, daily number) on a daily basis, to develop a deeper sense of quantity, counting patterns and place value, then students will increase their conceptual understanding and procedural fluency in number operations.

## Decomposing the Number of the Day - 63

ex: 63 = 60 + 3
60 = 50+10 and 3 = 2+1
50 = 20+30 and 10 = 5+5
(and so on and so on)

## Showing different ways to make the number 63.

- Base 10 (6 tens and 3 ones; 5 tens and 13 ones)
- Patterns (63+0; 53+10; 43+20; 33+30; 23+40; 13+50; 3+60)
- Combine and Remove (40+30-7; 50+50-37)

## Number Talks: What Does the Number Mean?

Tell me about the number 63:

- "6 tens and 3 ones"
- "My grandfather is 63"
- "I had 70 halloween candies and ate 7 of them. Now I have 63."
- " 20+20+20+3 = 63"
- "100-37 = 63"

## Choral Counting

Counting forwards and backwards by 1's, 2's, 5's, 10's, and 25's:

• Start at 5 and count up by 2's (5, 7, 9, 11, 13 ...)
• Start at 423 and count back by 10's (423, 413, 403, 393, 383, 373 ...)
• Start at 7 and count up by 5's (7, 12, 17, 22, 27, 32, 37 ...)
• Start at 25 and count up by 25's (25, 50, 75, 100, 125, 150, 175, 200 ...)
