4th Grade Math – Week of September 29, 2025

Dear Families,

This week in math, we are exploring different strategies for finding partial products in double-digit multiplication. Students will practice breaking apart numbers to multiply in smaller, more manageable steps—a foundational skill that supports deeper understanding of multiplication.

📝 Important Reminder

Our Chapter 4 Test will take place on Thursday, October 2. Please help your child review their notes and completed classwork to prepare for success.

📚 Fall Break Review Packet

An optional Fall Break Review Packet will be sent home this week. This packet is 100% optional, but it’s a great way for students to keep practicing and sharpening their skills during the break if they choose.

💡 How You Can Help at Home

Here are some simple ways to support your child’s learning this week:

  • Break numbers apart: Practice problems like 23 × 15 by rewriting them as (20 × 15) + (3 × 15).

  • Real-life examples: Ask your child to calculate totals when shopping or help with doubling recipes.

  • Visual models: Use grid paper or draw area models to show multiplication step by step.

  • Explain thinking: Encourage your child to talk through their process—explaining builds confidence and deepens understanding.

✨ As always, thank you for your continued support in helping your child grow into a confident mathematician!

Week of 9/22/25 🔢 Math – Multiplying Two-Digit Numbers

We are entering a new module in math focused on multiplying two-digit numbers. Students will learn and practice strategies for:

  • Estimating products

  • Using area models

  • Applying the Distributive Property

  • Calculating with partial products

Vocabulary Focus: Compatible numbers—numbers that are easy to multiply and close to the actual numbers in a problem.

At-Home Practice Ideas:

  • While shopping at a warehouse store, look for bulk packages (e.g., “1 large box contains 10 smaller boxes, and each smaller box contains 8 packs of fruit snacks”). Ask questions like:

    • What expression would you use to find the total in 1 large box? In 5 large boxes?

    • Can you think of other products packaged this way?

  • Look up ticket prices online for an event like a movie, museum, or theme park.

    • Write an expression for the total cost of tickets for a group of 10 people.

    • Ask: “What happens if one ticket price increases? How does the expression and total change?”

By the end of this chapter, students should feel confident applying strategies to multiply and using math in real-world situations.

🔢 Week of 9/15/25 Math – Multiplication with Partial Products

This week, we are working on using partial products to multiply. Students are learning to use place value to break apart multiplication problems, then add the parts together for the final product.

Success Criteria:

  • I can use place value to tell the value of each digit in a number.

  • I can write the partial products for a multiplication problem.

  • I can add the partial products to find a product.

Parent Tip: Ask your child to show you how they solve a multiplication problem using partial products—they should be able to explain each step clearly.

Week Of 9/8/2025- Math

Dear Parents and Guardians,

This week in math, our 4th graders will begin learning how to multiply one-digit numbers by two-digit numbers using the distributive property and expanded form. These strategies help students understand the structure of numbers and build a strong foundation for more advanced multiplication.

For example, instead of solving 6 × 23 all at once, students will break it into:
(6 × 20) + (6 × 3) = 138

🔍 Focus Skills This Week

  • Multiplying one-digit numbers by two-digit numbers using multiple strategies.

  • Applying the distributive property and expanded form to break apart numbers.

  • Reviewing 6-digit addition and subtraction (including regrouping) to strengthen accuracy with larger numbers.

🏡 How You Can Support at Home

You can help your child build confidence by practicing skills in everyday contexts:

  • Review multiplication facts (1–12) daily for quick recall.

  • Practice breaking numbers apart and solving in steps (e.g., “We have 4 packs of 16 juice boxes. How many do we have in total?”).

  • Encourage explanations—have your child talk through their strategy step by step.

  • Review addition and subtraction with regrouping through math games, apps, or quick practice problems.

🚀 Math Fluency with Rocket Math

This year, students in both 3rd and 4th grade will work hard on building math fact fluency through a system called Rocket Math.

What it looks like in class:

  • Oral partner practice and timed written practice (15 minutes daily).

  • Individualized pacing—students move through levels based on a placement test and their writing speed.

  • Motivation & celebration: Each time a student masters a fact set, they add a star to our class rocket. When the rocket is full, the class enjoys a celebration they helped choose—like pajama day or a math game day!

Important Notes:

  • Rocket Math is not graded and there are no punishments for progress speed.

  • Students who need extra support will receive small-group intervention with Mrs. Cundari during fluency time to strengthen conceptual understanding. These students will have alternative ways to earn stars but will still join in all class celebrations.

💡 Thank you for your continued support as we help our 4th graders become strong, confident mathematicians! Together, we can ensure they build the skills needed for success in both academics and real life.

Week of 9/2/25 Mathematics – Chapter 3: Multiplying by One-Digit Numbers
