Worked example
Count hundreds, tens, and ones separately, then combine their values.
0 × 100 + 2 × 10 + 3 = 23
- 0 × 100 + 2 × 10 + 3 = 23

Tips for Parents
▸ Why It Matters This is likely your child's first real practice with place value — the idea that where a digit sits changes what it's worth. The six problems use two-digit numbers like 23 and 54, each built from only a small number of ten-rods plus a handful of leftover ones-blocks, so nothing here asks your child to count more blocks than they can comfortably track with their eyes. That's a deliberate choice: the goal at this stage isn't speed, it's helping your child truly see that a ten-rod is worth ten single blocks bundled together, not just one block among many. This concrete, block-by-block understanding is the foundation every later place-value skill — reading three-digit numbers, comparing numbers, regrouping in addition and subtraction — will eventually be built on. ▸ Getting Started Before your child counts the blocks on paper, it helps to build the very same number with real objects if you have a few minutes — ten pennies bundled together with a rubber band and a few loose ones scattered beside them work particularly well, since the bundle mirrors the ten-rod shape on the page. Point at the bundle and say "this whole group is ten," then point at each loose coin and count it as one. Once your child has built and named a couple of numbers this way, the printed ten-rods and ones-blocks on the worksheet will make much more sense as symbols for the same idea. ▸ If They Get Stuck Have your child count the ten-rods first, one at a time, and then move to the loose ones-blocks separately — mixing the two groups together while counting is where most mistakes happen. Before writing the final number, get them to say it out loud as "X tens and Y ones," for example "five tens and four ones," and only then translate that into the written digits. This spoken step matters more than it might seem: the bundling idea, not just landing on the right digits, is the entire point of this sheet, and skipping straight to writing numbers can hide whether your child actually understands why 54 means five tens and four ones rather than just five and four. ▸ Praise Points Praise your child specifically for saying "X tens and Y ones" out loud before writing the number, rather than only celebrating when the final total is correct. That spoken step is proof they're thinking in organized groups of ten instead of just counting every block one by one from scratch, which is exactly the shift in thinking this worksheet is designed to build. If they get a number wrong, ask them to recount the ten-rods and ones-blocks separately rather than pointing out the mistake directly — catching their own error this way builds far more lasting understanding than a quick correction.
What This Worksheet Builds
This worksheet introduces the core base-10 idea using small, easy-to-see two-digit numbers like 23 and 54, each built from only a few ten-rods and a handful of loose ones-blocks. Your child practices counting the two groups separately, then combining them into a single number, learning that a ten-rod itself stands for ten single blocks rather than just one. Keeping the numbers small means every block stays visible at a glance, so the focus stays on understanding what tens and ones mean rather than on counting a large or unwieldy group.
Next Step
Once your child can count tens and ones separately without help and combine them into the right two-digit number, move on to Place Value Blocks 02. That next worksheet introduces round tens like 40 and 70, which have no ones-blocks pictured at all — a new challenge that asks your child to remember writing a placeholder zero even when there's nothing in the ones column to count.
