______the__two___models___are__different.
__________________________________________________________________________
__________________________________________________________________________

500 – 211 = 289.

Explanation:
In the above-given question,
given that,
the two strategies are the same.
why because the answer for the two strategies is the same.
5 hundred = 500.
2 hundred = 200.
1 ten = 10.
1 ones = 1.
200 + 10 + 1 = 211.
500 – 211 = 289.

Question 2.
Solve and explain why you chose that strategy.

 a. 220 + 390 = ________ 220 = 210 + 10. 390 + 10 = 400. 400 + 210 = 610 Explanation: __220_=__210__+__10________________ _____390__+__10_=__400______________ ___400__+__210__=__610_______________ __________________________ b. 547 – 350 = ________ Explanation: __________________________ __________________________ __________________________ __________________________ c. 464 + 146 = ________ Explanation: __________________________ __________________________ __________________________ __________________________ d. 600 – 389 = ________ Explanation: __________________________ __________________________ __________________________ __________________________

220 + 390 = 610.

Explanation:
In the above-given question,
given that,
I choose the number bond strategy.
220 = 10 + 210.
390 + 10 = 400.
400 + 210 = 610.

547 – 350 = 197.

Explanation:
In the above-given question,
given that,
I choose the number bond strategy.
547 = 10 + 537.
350 + 10 = 360.
360 + 537 = 897.

464 + 146 = 610.

Explanation:
In the above-given question,
given that,
I choose the number bond strategy.
146 = 6 + 140.
464 + 6 = 470.
470 + 140 = 610.

600 – 389 = 211.

Explanation:
In the above-given question,
given that,
I choose the number bond strategy.
600 = 1 + 599.
389 + 1 = 390.
390 – 601 = 211.

 1. 400 + 590 = ________ Explanation: __________________________ __________________________ __________________________ __________________________ 2. 775 – 497 = ________ Explanation: __________________________ __________________________ __________________________ __________________________

400 + 590 = 990.

Explanation:
In the above-given question,
given that,
I choose the number bond strategy.
590 = 10 + 580.
400 + 10 = 410.
580 + 410 = 990.

775 – 497 = 278.

Explanation:
In the above-given question,
given that,
I choose the number bond strategy.
497 = 5 + 492.
775 + 10 = 780.
780 – 492 = 278.
