Math CBA Next Week

Our first math CBA (Curriculum Based Assessment) is next Thursday, October 4th.  This CBA will cover each of the math concepts we have studied so far this year - place value, comparing and ordering numbers, addition and subtraction with regrouping, examples and nonexamples (looking at a group of objects and deciding how they are related and which other objects would fit into that group), and rounding to the tens place and hundreds place.  Here are some activities to help your child review for the CBA.  The rounding rhyme is what we use in class to to help students remember how to round to the nearest ten or the nearest hundred.

Rounding Rhyme

Underline the place to be rounded
Circle the number to the right

One through four - hold on tight

Five or more - watch it grow

Everything else turns into a ZERO

Another Rounding Rhyme

Find the number in its spot.
Go next door and see what you've got.
5 or more raise the score,
4 or less let it rest.
All the numbers to the right run to zero in a fright.

Spelling City

Spelling City has some great activities for students to practice spelling words.  Students can enter in their spelling words and play a game or take a test over their words.  There is a link to this site on the left side of the blog under the category "Useful Links".

Place Value

Place value is a concept that is difficult for some students.  In third grade, students are expected to read, write, and describe the value of whole numbers through 999,999.  Here are some games and websites to help students practice what we are learning about place value.
