Math Unit 2: Number Sense

We have started our second math unit. Students will be learning about place value (ones, tens, hundreds, thousands, ten thousands, and hundred thousands). They will need to:

1.  be able to read numbers up to the 100 000s place value. Have your child practice reading numbers to you wherever you can find them- flyers, the grocery store, gas stations, or make them up at home.
2. order numbers from least to greatest and greatest to least up to the 100 000s place value. See if your child and you can trick one another when you create numbers that look almost the same. Ask your child to tell you which trick they use to remember the least than sign (the small crocodile is always hungry and eats the bigger number, or that the less than sign looks like a tilted "L".

3. add and subtract 4-digit numbers by 4-digit numbers (without using a calculator). Students will need to know how to borrow and carry numbers. A helpful hint is to have your child draw light lines in their work in order to have the place values line up properly so that careless mistakes aren't made.



        4. multiply 4-digit numbers by 1 and 2-digit numbers. During this math unit students will not be allowed to use calculators to solve problems. They are expected to have their multiplication facts memorized. They will be allowed to use a multiplication chart to help them with their work. In class we have been playing multiplication memory match and the students love it. Try these games at home too. Students are also having weekly multiplication quizzes that are times. Each week review a multiplication table with your child at home. This week was the 3 times table. Next week will be the 4 times table.


5. know the 11s and 12s times tables. Again, practice these multiplication tables each night for 10 minutes with your child, in the car while your driving, when your getting ready for school, or making supper. A few minutes each day will really help your child with this unit, and almost all math in the future when their facts come quickly to them and they don't have to rely on drawing pictures to solve 1 step of a problem.

6. divide a 4-digit number by a 1-digit number. Again, working on multiplication facts is a great idea. Students will learn the language for the divisor, dividend, and quotient.


7. read and write numbers in written form, expanded form and standard form.
