Huge Hundreds Chart Lesson
//This procedure goes from easiest skill to hardest. Start with "Adding Tens" but move on as quickly or slowly as students need.//

Materials:


 * Set up the huge hundreds chart in the hall
 * Have mini hundreds chart and small frogs or dinosaur counters for students who are not walking on the chart
 * Dice to roll
 * White board and marker

Procedure:

ADDING TENS
 * First student rolls a dice and stands on that number. For example, he rolls a 4 and stands on the 4.
 * Teacher asks 4 + 10. Everyone moves to 14 (They may jump directly there, or count by ones.)
 * 14 + 10
 * 24 + 10
 * 34 + 10
 * Use your judgment. Once the student starts to go directly to the total, without counting by ones, continue about 3 more times using this pattern. Then, give them random problems to solve:
 * "Walk to 27. What's 27 + 10?"
 * 56 + 10
 * 79 + 10 (obviously, you have to change the numbers for each student's turn.)

SUBTRACTING TENS
 * If the student has mastered adding 10, move on to subtracting 10.
 * Start them at a high number and begin asking them to subtract 10. //You may need to ask them to point in which direction they will walk// //for subtraction.//
 * For example: 92 - 10
 * 82 - 10
 * 72 - 10
 * Again, once the student seems to have grasped the pattern, give them random problems:
 * 45 - 10
 * 87 - 10
 * 43 - 10
 * etc.
 * Mix up addition and subtraction!

ADDING MULTIPLES OF 10
 * If the student has mastered adding and subtracting 10, move on to adding multiples of 10. //You may need to remind them to decide which direction to walk in.//
 * 45 + 20
 * 39 + 20
 * 56 + 30
 * 38 + 40
 * etc.

SUBTRACTING MULTIPLES OF 10
 * If the student has mastered adding multiples of 10, move on to subtracting multiples of 10. //You may need to remind them to decide which direction to walk in.//
 * 67 - 20
 * 56 - 20
 * 98 - 20
 * 34 - 20
 * 53 - 30
 * 75 - 30
 * 89 - 40
 * etc.
 * Mix up addition and subtraction!

JUMPING TENS AND ONES
 * If the student has mastered subtracting multiples of 10, move on to tens and ones.
 * Start with problems that add ten plus just a few ones, like:
 * 34 + 12 //If they are stuck or start counting by ones, help them break 12 into 10 + 2, for example. Suggest that they do 34 + 10, then add 2 more.//
 * 56 + 14
 * 21 + 11
 * Then move on to more ones.
 * 65 + 17
 * 41 + 19
 * 22 + 18
 * Then move on to more than one ten.
 * 45 + 23
 * 67 + 34
 * etc.
 * Next do subtraction in the same way, with one ten and only a few ones, then getting harder and harder.
