@BurgosKelly_V do you happen to have the math student growth graphic that shows the projected growth of students based on the different teaching methods? I believe one of the categories was choice and students grew 1.5 grade levels in a calendar year???

@ChiTiger83 @josephngata Thanks!

T and Addy with the find this morning. #jngatascav @josephngata

Finally, we can halve 2 and double 152, giving us 1x304. Since 1x304=304, 16x19=304.

Doubling and halving is a great strategy to multiply mentally. For the problem 16x19, we can halve 16 and double 19, giving us the problem 8x38. We can again halve 8 and double 38, giving us the problem 4x76. Yet again, we can halve 4 and double 76, giving us 2x152.

Ask your student about their choice board for this week. Activities can be completed in class and worked on at home. Each student is expected to complete their points by Friday!

Do you have a nightly routine for your child? How about adding a nightly math problem to your routine. Visit https://t.co/nYj1hj27zz for a nightly math story and discussion question! #mentalmathmonday

Use estimation to check for reasonableness of these problems:

53 x 31
62 x 88

[Greg Sullivan @SullivanRAV]

Estimating is a great way to check for reasonableness. For 32 x 28, we can estimate the product by rounding both factors to 30. Since 30 x 30 equals 900, we can check to see if our answer makes sense after we complete our work. #mentalmathmonday

Equivalent names for numbers are names that represent the same number. For example, an equivalent name for 20 maybe 19+1 or 4x5.

Find 3 equivalent names for 35. Challenge: Use multiple operations and parentheses in your equivalent names!

When adding 56 + 27 using the front-end strategy, think of 50+20=70 and 6+7=13, so 56+27=83. Use the front-end strategy to add the following:

What is 14 x 13? Use a mental math strategy to find the product.

Bonus: Find multiple strategies to find the product. #mentalmathmonday

#askuniversal I bought a shirt last week in Hogsmeade and when I returned to SC, it still had the ink tag. Any ideas on how to remove it?

Thanks to @KierMeredith for the baseball!

@salkhanacademy are there any plans to add reports to the Khan Academy MAP practice for teachers?
