What Your Child Will Learn
- Count concrete objects accurately from 1 to 20 using one-to-one correspondence
- Identify and write numbers in sequence from 1 to 20 without skipping or reversing digits
- Apply skip counting patterns by 2s up to 20 (2, 4, 6, 8, 10, 12, 14, 16, 18, 20)
- Demonstrate skip counting by 5s up to 20 (5, 10, 15, 20) using visual patterns
How to Use This Worksheet
- Step 1: Begin with the object counting section - have your child point to each object while counting aloud to establish one-to-one correspondence
- Step 2: Move to number sequence problems - encourage writing numbers carefully and checking that teens numbers (11-19) are written correctly, not reversed
- Step 3: Practice skip counting by 2s using the worksheet problems, having your child circle or mark every second number to visualize the pattern
- Step 4: Complete skip counting by 5s activities, connecting to familiar concepts like counting by fives on fingers or clock face numbers
- Step 5: Review completed work together, focusing on any errors in number formation or counting sequence to reinforce correct patterns
Tips for Parents & Teachers
When counting objects, encourage your child to touch or point to each item as they say the number aloud to prevent double-counting or skipping items - this builds one-to-one correspondence skills
Watch for number reversals common in Grade 2, especially with numbers 12-20 where children might write '21' instead of '12' - practice writing these numbers while saying them out loud
For skip counting by 2s, use pairs of objects like socks or shoes to make the pattern visual and meaningful rather than just memorizing the sequence
If your child struggles with skip counting by 5s, connect it to counting fingers on hands or use nickels to show the 5-cent pattern they may already know
Frequently Asked Questions
My child can count to 20 but mixes up the written numbers 12-19. Is this normal?
Yes, this is very common in Grade 2! The teen numbers are tricky because we say 'twelve' but write '12', not '21'. Practice writing these numbers while saying them aloud, and use number cards to match spoken numbers with written forms.
How can I help my child understand skip counting if they're still learning regular counting?
Start with concrete objects arranged in groups. For counting by 2s, use pairs of items like shoes. For counting by 5s, use groups of 5 toys. Let them count each group normally first, then show how skip counting jumps over the numbers in between.
Should my Grade 2 child memorize skip counting patterns or understand why they work?
Both! At this age, some memorization helps build fluency, but understanding makes it stick. Use visual patterns like dot arrays or number lines to show why we land on certain numbers when skip counting.
My child counts objects correctly but loses track with larger groups. What should I do?
This is normal for 7-8 year olds. Teach them to organize objects in rows or lines before counting, cross out or move counted items, or count in smaller groups of 5 or 10 first, then add the groups together.
How do I know if my child is ready for skip counting by 10s after mastering 2s and 5s?
Once they can confidently skip count by 2s and 5s to 20 without hesitation and understand the patterns, they're ready for 10s. Skip counting by 10s is often easier because it follows a clear pattern (10, 20, 30) that connects to place value concepts.
