Part-whole bar models for join and compare story problems.
Bar modelsVertical addition with carrying in the ones and tens columns.
RegroupingMental math shortcuts for adding within 20 without counting on fingers.
Within 20Break numbers up to 10 into two parts — the foundation before bar models.
Number bondsFluently add and subtract multi-digit numbers with the standard algorithm.
Multi-digitA quick fluency sprint for addition facts within 20 — great for nightly warm-ups.
Within 20Singapore CPA visual models + California Common Core alignment — built for parent-led practice.
Singapore-style CPA progression starts with dot strips and number bonds kids can touch and count, moves to bar models for story problems, then column addition — never jump straight to symbols alone.
Kindergarten puts sets together within 10; 1st grade adds bar models and fluency within 20 with unknowns in all positions — the skills teachers expect on homework and assessments.
Column addition with carrying connects to tens-and-ones understanding so regrouping is a strategy, not a trick to memorize.
Why parents switch from ad-heavy worksheet sites and expensive workbooks.

A simple parent workflow — no prep, no screens.
Filter by grade and topic — number bonds for K, bar models for 1st, regrouping for 2nd — preview live and pick a seed that fits what your child worked on today.
Run a 10–15 minute addition sprint at the kitchen table — no screens, no login, just the PDF you previewed with a pencil and eraser.
Use a new seed for fresh addition problems on the same skill so nightly practice stays familiar in format but new in numbers.
“My son kept mixing up carrying in column addition — the 2nd grade regrouping sheets finally clicked because the layout matches what his teacher sends home in Milpitas.”
“We do ten minutes of addition before bed in Hyderabad. Download, print, done — no ads, no signup, and a different problem set every night.”
“The number bond trees bridged perfectly from kindergarten to 1st grade bar models. My daughter actually asks for “one more addition page” now.”
Yes. Every addition worksheet on Kibi Club is free to preview in your browser and download as a PDF with one click. No account, subscription, or paywall.
Start with your child’s grade. Kindergarten focuses on putting together within 10 and number bonds; 1st–2nd build fluency within 20 and bar models; upper grades practice multi-digit addition with regrouping and the standard algorithm.
Yes. Each worksheet uses a seed number so you can shuffle to a fresh problem set and print again — useful for nightly practice without repeating the same sheet.
Topics follow California elementary math standards (CCSS-aligned): K.OA for early addition, 1.OA for within-20 fluency and bar models, 2.NBT for column addition with regrouping. Open a grade filter on /worksheets to see addition topics for that band.
Yes. Compiler worksheets include QR-linked answer keys on the theme footer so you can check work quickly after the sprint — unless the template opts out (e.g. early tracing sheets).
Go back to number bonds and make-a-ten strategy sheets (K and 1st grade) before jumping to column addition. Regrouping sticks when kids see tens and ones, not just “carry the 1.”
