Five pages on putting three numbers up to 1,000 in order. Page 1 shows each number in base-ten blocks: students count the hundreds, tens and ones, write the three numbers, then write them from least to greatest, with a worked example first. Page 2 starts with a tip about comparing the hundreds first, then has ten sets to order from least to greatest, most of them sets that share digits, like 356, 365 and 536, or 409, 490 and 94. On page 3 students write eight sets on a set of stairs, the greatest on the top step. Page 4 has number lines from 0 to 1,000 by hundreds, 300 to 400 by tens and 740 to 750 by ones: students write the number each arrow points to and order the three, then draw dots for 650, 150 and 850 on a 0 to 1,000 line. Page 5 orders the weights of three zoo animals, three game scores and three town sizes, asks who has the most or the least, and makes the greatest and least 3-digit numbers from digit cards.
Before page 1, have three students each build a number with base-ten blocks, like 213, 132 and 231, and ask the class to line the students up from least to greatest. Talk about why the hundreds decide it first. For page 4, make a floor number line from 300 to 400 with tape and let students stand on 320, 370 and 390. The digit cards on page 5 make a good partner game with real cards.
Look for 3-digit numbers around you: page numbers, prices, house numbers. Pick three and ask your child to put them in order from least to greatest, then from greatest to least. Write three digits on scraps of paper and take turns making the greatest and least numbers you can.
