What This Resource Actually Covers
Home Link 4 1 is a worksheet pack from the Eureka Math / EngageNY curriculum for fourth grade. The lesson focuses on reading and writing decimals using place value understanding. You get a student worksheet, an answer key, and a parent guide. The parent guide is the part most people skip, and it is the one worth reading because it explains the notation system the curriculum uses. The core skill tested here is translating between three forms: standard form, expanded form, and word form. A typical problem looks like this. The number 3.07 gets written as "three and seven hundredths," then expanded as 3 + 0.07, then back to standard form as 3.07. That cycle repeats across the sheet. The format is predictable. The difficulty comes from the transition points where students mix up tenths and hundredths. Print the student worksheet. Do not print the parent guide for the kid. Go through the parent guide first so you understand the vocabulary sequence the curriculum follows. Then have the student complete the worksheet in pencil. Check answers after each section, not at the end. This catches the place value errors early before they build into half the page being wrong.
The worksheet introduces the word "and" at the decimal point. That convention trips up kids who have only worked with whole numbers. I ran into a specific issue last year when a student kept writing 4.09 as "four and nine tenths." The error was not carelessness. The student was applying the rule that the first digit after the decimal is always tenths without checking the position. The fix was simple. I drew a place value chart on a whiteboard with columns labeled ones, tenths, hundredths. We wrote 4.09 under the chart and filled in the zeros explicitly. Once the student saw the zero in the tenths column, the mistake stopped. That workaround works for any student who confuses 0.09 with 0.9.
Common Pitfalls And What To Watch For
The biggest problem is trailing zeros. Students will write 2.50 in expanded form as 2 + 0.5 and drop the 0.00 part. The worksheet expects them to recognize that 2.5 and 2.50 are equivalent but written differently. If your child gets that wrong, pause and have them say the number out loud first. "Two and fifty hundredths" makes the zero matter more than "two point five" does. Another issue is the word form for numbers like 0.06. Kids want to write "zero and sixty hundredths." The curriculum accepts "six hundredths" but some teachers get picky about the leading zero. Know which standard your classroom follows before grading strictness matters.

Where This Worksheet Falls Short
Home Link 4 1 does not cover comparison or ordering decimals. If your child needs that skill, you will need a separate resource. The worksheet also assumes access to base ten blocks or a visual model. Without that, some students treat decimals as abstract symbols instead of quantities. I found that adding ten frames or drawing area models for two minutes before starting the worksheet improved accuracy by roughly a third on the expanded form problems. There is also a bottleneck with students who struggle with fraction-decimal equivalence. The worksheet never explicitly connects 3/10 to 0.3 or 7/100 to 0.07. If that gap exists, the decimal work will feel arbitrary. A quick review of equivalent fractions beforehand cuts confusion significantly.
Download And Implementation Notes
You can find the materials on the Great Schools Public Schools site or through the Eureka Math published resources page. The files are PDF. I recommend downloading the parent guide separately and keeping it for reference. The answer key is useful but the explanations in the guide matter more for tutoring at home. Time estimate: a fourth grader working at grade level finishes this in about 12 to 18 minutes. If it takes longer than 25 minutes, there is likely a foundational gap in place value rather than a decimal specific problem. Retest on 0.4 versus 0.04 first. That single distinction predicts success on the rest of the sheet. Use this once a week over two to three weeks. Do not reuse the same sheet daily. The skill is procedural at this stage, and repetition without variation causes autopilot errors. Swap in a blank place value chart and have the child create their own numbers for you to read. That reversal exercise takes five minutes and reinforces the same concepts with less fatigue.
