Before Grade 1, the number 34 is just a word that comes after 33. Now it becomes three bundles of ten and four loose ones. That shift is the first real step into place value.
These sheets use the Tens and ones variant. Each problem draws long rods for tens and small squares for ones, and your child writes the number the blocks make. The easy level keeps the pictures small. The hard level uses larger two-digit numbers with more rods to read.
The common slip is counting every block as one. A child who sees 4 rods and 3 squares may write 7. Teach the habit of counting the rods by tens first, then adding the squares on the end. Numbers like 20 or 60, with no squares at all, also make kids pause, because the missing ones feel like a mistake.
Begin at the easy level and stay there until your child reads the blocks without pointing at each one. Move up after two sheets in a row go smoothly. A handful of craft sticks and a rubber band make a good table demo: bundle ten, then build a number together.
