Summer Math: Numbers 11-20
Written by Adi Ackerman, Head Teacher
"Summer Math: Numbers 11-20" is written for Kindergarten (Ages 5-6). If your little one is a year younger but already steady on summer activities, the page still works. You may just need to read the instructions out loud. And if they are older and counting to 20 never quite stuck, this is a short review rather than busywork.

What does this resource teach?
⌄
This printable summer resource gives Kindergarten students a seasonal activity, whether that's a coloring page, matching game, craft, or a skill-practice resource with a summer theme. Use it for end-of-year fun, a summer learning packet, or anytime a seasonal twist helps keep kids engaged.
Can I use this counting to 20 resource for homeschool or classroom?
⌄
Yes, both. We made it for Kindergarten summer activities, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with counting to 20. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
What does this cover?
⌄
Counting and numeral work across 11 to 20, the teen numbers, in a summer theme. These are the hardest numbers in early math, so they benefit most from practice over a break.
Why are the teen numbers so difficult?
⌄
Because the names fight the notation. Eleven and twelve give no clue at all, and thirteen through nineteen say the ones digit first while the ten is written first. Children who count to 100 confidently often still stumble here.
What helps with the teens?
⌄
Show that each teen is a ten and some more, using a ten frame or ten counters plus extras. Seeing that 14 is a full ten and four makes the name and the numeral agree, which listening alone never does.
How many Kindergarten counting to 20 resources are there?
⌄
1 printable resource, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.
What age are counting to 20 resources for?
⌄
These are written for Kindergarten students, roughly ages 5-6. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.
Can I use these counting to 20 resources for homeschool?
⌄
Yes. Nothing here assumes a classroom of 25, so they work the same one-to-one at the kitchen table as they do in a Kindergarten classroom, a literacy centre, or a tutoring session.
