Measuring Lengths Indirectly – order three objects and measure the length of 2 objects by using a third object, using nonstandard units

*At home, you can measure objects using paper clips, Goldfish crackers, or any other small object, and have your child line up the objects measured from longest to shortest and the reverse.

Use these sites and search for measuring with only centimeters and inches.

Add and subtract within 100 to solve one- and two-step contextual problems, with unknowns in all positions, involving situations of add to, take from, put together/take apart, and compare. Use objects, drawings, and equations with a symbol for the unknown number to represent the problem.

* Parents can make up contextual problems at home- for example:

Johnny had 15 toy cars and his friend Ritchie gave him some more. Johnny now has 24 toy cars. How many cars did Ritchie give Johnny?

15+a = 24

Generalize place value understanding for multi-digit whole numbers.

I can recognize that in a multi-digit whole number, a digit in the ones place represents ten times what it represents in the place to its right.

Ex: The digit 7 in 7,436 in ten times greater than the digit 7 in 5,735

I can read and write a multi-digit whole number using numerals, words, and in expanded form.

Ex:

218,942 --- Standard Form (Numerals)

two-hundred eighteen thousand, nine hundred forty two --- Word From

200,000 + 10,000 + 8,000 + 900 + 40 +2 (Expanded Form)

I can compare two multi-digit numbers using <, >, = by using what I know about the values in each place.

Ex: 456,842 > 453,802

I can round multi-digit whole numbers to any place.

234,560 rounded to the nearest hundreds place would be 234,600
