Q1.
Circle groups of ten 1s, 10s, and 100s as many times as required in each of the following pictures. Fill in the empty boxes. — e) 11 Tens and 14 Ones. ______ Hundred + ______ Tens + ______ Ones = ______
Part (e): 11 rods of ten and 14 single blocks.
HundredsTensOnes
???
?
Answer
Part (e): 11 rods of ten and 14 single blocks.
14 Ones = 1 Ten + 4 Ones
11 Tens + 1 Ten = 12 Tens
12 Tens = 1 Hundred + 2 Tens
100 + 20 + 4 = 124
After regrouping: 1 flat, 2 rods and 4 single blocks.
1 Hundred + 2 Tens + 4 Ones = 124
HundredsTensOnes
124
Why it happens: we regroup twice — ten ones into a rod, then ten rods into a flat. Each box can hold only 0 to 9.
Q2.
Circle groups of ten 1s, 10s, and 100s as many times as required in each of the following pictures. Fill in the empty boxes. — f) 1 Hundred, 12 Tens and 14 Ones. ______ Hundreds + ______ Tens + ______ Ones = ______
Part (f): 1 flat, 12 rods of ten and 14 single blocks.
HundredsTensOnes

Answer
Part (f): 1 flat, 12 rods of ten and 14 single blocks.
14 Ones = 1 Ten + 4 Ones
12 Tens + 1 Ten = 13 Tens
13 Tens = 1 Hundred + 3 Tens
1 Hundred + 1 Hundred = 2 Hundreds
200 + 30 + 4 = 234
After regrouping: 2 flats, 3 rods and 4 single blocks.
2 Hundreds + 3 Tens + 4 Ones = 234
HundredsTensOnes
234
Why it happens: the hundred we already had joins the new hundred made from ten rods, so the Hundreds box shows 2.
