This free printable Grade 1 mathematics worksheet builds place-value understanding through 20 multiple-choice questions. Students count base-ten blocks to identify two- and three-digit numbers, combine 10 with additional ones, recognize that 10 ones equal 1 ten, and decompose numbers such as 13 and 10 into tens and ones. The worksheet gives students repeated practice connecting concrete block models with written numerals and place-value descriptions. It is useful for introducing or reviewing how groups of ten are formed and how leftover ones are represented. Teachers can use the questions for independent practice, small-group instruction, or a quick check of foundational number sense. A complete answer key is included with this free printable worksheet.

This Grade 1 worksheet uses 20 multiple-choice questions to practise reading numbers represented by base-ten blocks and expressing numbers as tens and ones. Students also identify combinations such as 10 and 2 making 12, recognize that 10 ones equal 1 ten, and decompose numbers such as 13 into 1 ten and 3 ones.
Begin by modeling one or two base-ten block questions, asking students to identify the tens and then count the remaining ones before choosing a numeral. Next, connect the models to the worksheet’s number-composition items, such as 10 and 6 making 16, and explicitly trade 10 ones for 1 ten. Use the final tens-and-ones questions to have students explain why 10 is 1 ten and 0 ones.
Students may count individual blocks without grouping 10 ones as 1 ten, causing errors when reading numbers such as 108 or 115. They may also reverse the tens and ones when interpreting statements such as 13 = 1 ten 3 ones, or select 1 ten 1 one for 10 instead of 1 ten 0 ones. Ask students to point to the tens and ones in the model or equation before selecting an answer.
