Carter says a reasonable estimate for 274 x 8 is 1,000. Emma says a better estimate is 2,000. Who made the better estimate AND why?
Emma made a better estimate. 200 x 8 is already 1,000, and 70 x 8 is going to be around 560, so the answer will be closer to 2,000 than 1,000.

Use partial products to show 43 x 6.
(40 x 6) + (3 x 6) =
240 + 18 = 258
43 x 6 = 258
Use partial products to show 7 x 133.
(100 x 7) + (30 x 7) + (3 x 7) =
700 + 210 + 21 = 931
Use partial products to solve the problem.
1,245 x 3 =
(1,000 x 3) + (200 x 3) + (40 x 3) + (5 x 3) =
3,000 + 600 + 120 + 15 = 3,735
1,245 x 3 = 3,735
Use partial products to solve the problem.
22 x 14
(10 x 20) + (10 x 2) + (4 x 20) + (4 x 2) =
200 + 20 + 80 + 8 = 308
22 x 14 = 308

Use the digits 1, 2, 3 and 4 to write a 2-digit by 2-digit multiplication problem, using each digit only once. Solve your problem.
Many possible combinations, for example:
12 x 34 =408
14 x 23 = 322
23 x 41 = 943
There are 116 horses on the farm. Each horse has 3 ponies. How many ponies are there altogether?
There are 348 ponies.
Kelly says the product of 42 x 6 is bigger than the product of 32 x 8. Is she correct? Explain your thinking with numbers or words.
Kelly is incorrect, because the product of 42 x 6 is 252 and product of 32 x 8 is 256.
*many possible answers. for example:
900 x 6 = 5,400
800 x 7 = 5,600
