Lesson Plan for Student Book BI, Page 4 19 4E Teacher Guide 2 O BJECTIVE : To show a number with blocks and a picture. M ATERIALS : Base ten blocks, Place Value Mat (Masters 1 and 2) Multi-Digit Numeration To assist development of the understanding of multi-digit numeration, provide practice with the following activities: 1. Writing numerals from blocks Display a set of ones, tens and hundreds blocks. At first do not use ten or more of any one kind of block. Ask the students to describe what they see. Ask how they would record what they see. Repeat with a different set of blocks. When students are able to correctly record the numeral, display a set of blocks having 10 or more ones blocks so that students must exchange 10 ones for 1 ten before recording. Then display a set of blocks having 10 or more tens blocks so that students must exchange 10 tens for 1 hundred block before recording. Finally, display a set of blocks having 10 or more ones blocks and 10 or more tens blocks. This activity provides readiness for the regrouping in whole number addition and subtraction. 2. Building blocks from numerals Write a 3-digit numeral on the chalkboard, avoiding the use of zero at this time. Ask students to explain what each digit in the numeral means. Ask how to read this number. Then ask them to build the number with base ten blocks. This activity can be practiced in pairs with one person writing a numeral and the other person saying and building the number with base ten blocks. 3. Building blocks and writing numerals from oral presentation Teacher says a 3-digit numeral out loud. (Two hundred sixty-five.) Students build the number with base ten blocks and then record the numeral. 4. Drawing pictures of numerals Use your blocks to build 537. Place the blocks on your Place Value Mat. Read the number aloud. (five hundred thirty-seven) Show students how to draw a picture using a small square for each hundred, a stick or straight line for each ten and a dot for each one. Direct attention to the top of the page. Have students use blocks to show the number 342, draw a picture of the number ( aaassssf )and write the number in expanded form. Have students complete the page on their own.
