Have children group and count items in the classroom, such as paper clips, collections, and so on.
Use the language of place value when you make any groupings.
Once children have grasped the concepts of place value in the hundreds, introduce money amounts using decimal notation.
Some children may have trouble writing the number in the hundreds place and write the hundreds number out, e.g., 20035 for 235. Use the place value mat to illustrate and write the number that represents each digit.
Strategy Tip:
Materials: Beans, Popsicle Sticks Procedure: 1. Place a pile of beans on each table and show how it is easier to count them in groups of ten. 2. Have students glue ten beans on each popsicle stick; a filled stick is one ten-group. 3. Students can then bundle them together with rubber bands and introduce the words, twenty, thirty, forty, etc. 4. Count any leftover beans as separate units (ones). Note: Counting in groups will help students understand more complex concepts such as multiplication.
When Students Ask:
Why should I learn this? Encourage children to see that they will need to write greater numbers, as in money and in greater quantities of items.
If I hear a number without seeing it, how do I know what to write? Give children practice with this skill. Remind children that when hearing a number, they must listen carefully. If they hear that the number is something hundred, they will have three numbers, just as their mat has.
Why can't I put the numbers in any order? It is important to emphasize the order of the numbers. Use lots of examples. For example, write 285 on the chalkboard. Ask children if they would rather have 285 stickers or 852 stickers. Point out how important it is to listen to and write the order of numbers correct.
