I start with larger numbers, like 20 and rounding numbers. Start with 20 and 19, which is close to 20...makes 40 but remove one. Then same with 18 and 17. Then round 16 to 15 and mentally add it from there. As the numbers decrease, then I would add on...added groups of numbers together (e.g.,  1,2,3,4,5,6), then keep going and group them into friendly numbers.

Pairs to make  the sums of 20

I started with 20, 19+1, 18+2 and so on, till I came to 10

I grouped numbers to make sums of twenty to count by twenties until I got the remaining number (which was 10)

Start with 1+2+3.....

210 ... I noticed I could make 10 sets of numbers that add up to 21 (1 + 20, 2 + 19, 3 + 18, etc), so I multiplied 21 by 10 to get 210.

Add first and lasts - always 21....multiply by 10

10 pairs of 20 + 10

210, First I added all 10s and then the digits in tens place in double digits. Finally, I added all single digits

I followed others' lead and grouped numbers together, got 10 groups of 21, which equals 210
