This is a complete lesson v examples and also exercises about two-digit divisor in lengthy division, meant for initial teaching in 5th grade. The an initial exercises have grids to complete the division, and an are for student to compose the multiplication table that the divisor in the margin. Then there space conversion problems in between inches/feet and also ounces/pounds, because those are addressed with division.

 Often, the is beneficial to write the multiplication table the the divisor before you divide. Example 1. The division is by 16. Right here is the multiplication table of 16:3 × 16 = 484 × 16 = 645 × 16 = 806 × 16 = 96 7 × 16 = 112 8 × 16 = 128 9 × 16 = 144 0 3 16 ) 5 5 6 8

16 goes into 5 zero times, so we look in ~ 55.

How many times does 16 go into 55?

Check in the table onthe left. We check out it walk into55 3 times.

 0 34 16 ) 5 5 6 8 - 4 8 7 6

Now, how many times walk 16 get in 76?

From the table we deserve to see that it is four times.
 0 3 48 16 ) 5 5 6 8 - 4 8 7 6 - 6 4 1 2 8 - 1 2 8 0

Lastly, 16 goes right into 128exactly 8 times, and also thedivision is over.

Example 2. us are splitting by 32. Here is the multiplicationtable of 32:

3 × 32 = 964 × 32 = 1285 × 32 = 1606 × 32 = 1927 × 32 = 2248 × 32 = 2569 × 32 = 288
 0 1 32 ) 4 7 0 7 - 3 2 1 5

32 goes into 47 once.

 0 1 4 32 ) 4 7 0 7 - 3 2 1 5 0 - 1 2 8 2 2

32 goes right into 150four times.
 0 1 4 7 32 ) 4 7 0 7 - 3 2 1 5 0 - 1 2 8 2 2 7 - 2 2 4 3
32 goes into 224 seventimes. Notice there is a remainder. 1. Divide.First compose a multiplication table for the divisor. Check each prize by multiplying.
