DAY 3
Practice 4 (PR1ME pp. 31–32)
Work through the exercises together.
Task 1(a): Tell students to use the picture to compare the numbers. Guide students to start by comparing the hundreds, and conclude that since 2 hundreds is smaller than 5 hundreds, 214 is smaller than 525. Task 1(b): Point out to students that since the number of hundreds is the same in both numbers, they have to compare the tens. Guide students to conclude that since 7 tens is greater than 6 tens, 374 is greater than 362. Task 1(c): Point out to students that since the digits in the hundreds and tens places of the two numbers are the same, they have to compare the digits in the ones place. Guide students to conclude that since 9 ones is greater than 5 ones, 309 is greater than 305.
Task 2: Guide students to compare two numbers within 1000 by writing ‘greater than’ or ‘smaller than’.
Teaching Tips
➢ Highlight to students that they have to start comparing numbers by looking at the digits in the greatest place value. Point out that they need to compare the digits in the tens place only if the digits in the hundreds place are the same. ➢ Remind students to use the symbols ‘>’ and ‘<’ correctly. You might wish to point out that they can imagine the symbol for comparison as the mouth of a hungry crocodile, which will open its mouth to swallow the greater number. So, the ‘opened mouth’ will point towards the greater number.
