What Your Child Will Learn
- Identify and count individual blocks in visual block models to represent numbers up to 10
- Solve addition problems by combining two groups of blocks and finding the total sum
- Understand part-whole relationships by recognizing how two smaller numbers combine to make a larger number using block models
- Apply addition strategies by using visual blocks to demonstrate commutative property (e.g., 3+2 equals the same as 2+3)
How to Use This Worksheet
- Step 1: Start with the first problem and have your student look at the first group of blocks. Ask them to count and say the number aloud, touching each block if needed.
- Step 2: Direct attention to the second group of blocks and have them count this group separately. This reinforces understanding that there are two distinct parts being combined.
- Step 3: Guide your student to count all the blocks together (or use 'counting on' if they're ready) to find the total. Have them write or say the complete addition sentence (e.g., '3 plus 2 equals 5').
- Step 4: Repeat this process for each of the 15 problems on the worksheet, gradually reducing the amount of support you provide as their confidence grows.
- Step 5: After completing the worksheet, review 2-3 problems together and ask your student to explain what the blocks showed them about how two numbers combine.
Tips for Parents & Teachers
Students at this level often struggle with the transition from counting objects to understanding that blocks represent abstract quantities. Encourage them to physically touch and move blocks while saying numbers aloud to strengthen the connection between visual representation and number value.
Watch for students who recount the entire group instead of using 'counting on' strategies. After they identify the first group, prompt them to start counting from that number rather than starting over at 1. For example, if they see 4 blocks, help them say '4' and then count on: '5, 6' when adding 2 more.
Many Grade 1 students confuse the total with just the last block they counted. Reinforce that the final number they say represents ALL the blocks combined. Point to the entire group and say 'This whole group of blocks equals [number]' to emphasize the total.
Use consistent language with block models: 'We have [first number] blocks here, and [second number] blocks here. When we put them together, we have [total] blocks.' This consistent verbal scaffolding helps students internalize the addition concept.
Frequently Asked Questions
Why are we using blocks instead of just teaching addition facts?
Block models help Grade 1 students develop number sense and understand that addition is about combining groups. When children can SEE and TOUCH blocks, they build a concrete understanding of what addition means. This visual foundation helps them later solve addition problems mentally and understand more complex math concepts. The blocks show them that 3+2 is the same as 5 blocks total, making the abstract idea of addition concrete and meaningful.
My child keeps recounting from 1 instead of counting on. Should I be concerned?
This is completely normal for Grade 1! Recounting is actually an important developmental stage. However, you can gently introduce 'counting on' by saying something like: 'We have 4 blocks here already. Let's start at 4 and count on: 4...5, 6. We added 2 more blocks.' With repeated exposure and your modeling, most first graders naturally transition to counting on within a few weeks or months. Don't rush this—let them build confidence with recounting first.
What if my child struggles to understand that the blocks represent the numbers?
Some Grade 1 students need extra time to connect symbols (the numbers 3, 4, 5) with quantities (blocks). Help by always saying the number aloud while pointing to the blocks: 'This is 3—one, two, three blocks.' Use real objects from around your home (buttons, crackers, coins) alongside the worksheet blocks so they see that the same quantity can be represented in different ways. The more they experience this, the faster the connection clicks.
Should my child memorize facts or use the blocks to figure out every answer?
At this stage, using blocks to figure out answers is perfect! Grade 1 students are building understanding, not yet automaticity. Let them use the blocks to solve every problem on this worksheet. Memorization will develop naturally over time as they see patterns repeated. Some facts may stick (like 1+1, 2+2), but that's a bonus—the real goal right now is deep understanding of what addition means.
