Grade 5 Science: Content Coverage Versus Science Practices
A fifth-grade science teacher reviews MAP Growth Science results for 24 students. The class median RIT is 201; the national median for the grade is 203. Instructional-area data show relative strength in Life Science (median 207) and weakness in Earth and Space Science (median 196). However, the teacher notices that many students who score high in Life Science also miss questions requiring them to analyze data from a table and justify a conclusion. The next unit is on Earth's systems, specifically the water cycle and human impact. The district requires a hands-on investigation and a written claim-evidence-reasoning (CER) paragraph. The teacher has 40-minute periods, four days per week, for three weeks. A few students have RIT 215+ and finished the prior unit early; several have RIT below 190 and struggle with grade-level text. The teacher must decide whether to spend limited time on Earth/Space content, science practices, or both, and how to differentiate.
1. Analyze the class data. Which need is better supported: reteaching Earth and Space content or teaching data-analysis and CER practices? Explain the limits of the evidence.

The data support a combined focus, not an either-or choice. The Earth and Space median of 196 is 11 points below Life Science (207), but with typical RIT error of a few points and only 24 students, that gap is a reasonable signal, not a precise diagnosis. The more instructionally specific evidence is that high Life Science scorers still miss table-analysis and justification items; that pattern points to science practices (data interpretation and CER) that cross content areas. Teaching practices without content would be generic; reteaching Earth content without practices would not address the observed item pattern. Therefore, integrate: use the water-cycle and human-impact content as the vehicle for data analysis and CER. Avoid claiming that the class is weak in Earth Science based solely on the median; check the item-level report and classroom work. Also note that MAP Science is an interim measure, not a curriculum mastery test.
2. Plan the three-week unit sequence with specific differentiation for high- and low-RIT students, keeping all students on the same core investigation.

Three-week sequence, four 40-minute periods per week. Week 1: whole-class investigation of evaporation and condensation using a simple model; students record data in a table and write a prediction. Week 2: human impact on water systems; students analyze a provided dataset (for example, runoff or water use) and identify patterns; mini-lesson on axes, scale, and outliers. Week 3: CER paragraph; students make a claim about a water-system change, cite data, and explain the science. Differentiation: students with RIT below 190 get a partially completed data table, a word bank, partner reading, and a CER sentence frame; students at 215+ get an extension requiring them to critique the investigation design or calculate a derived value. All students participate in the same core investigation and write a CER paragraph; extensions deepen rather than replace. Use flexible pairs, not permanent groups.
3. What formative and summative evidence would show whether the plan worked, and how would the teacher adjust if MAP-like practice scores do not improve?
Read the worked answer
Formative evidence: exit tickets asking students to choose the best claim supported by a table, a mid-unit data-analysis probe, and a CER draft scored with a shared rubric. Summative: an individual CER paragraph on a new but related dataset, plus a short transfer task. Track whether students can select relevant data, not just recall water-cycle terms. If MAP-like practice scores do not improve, first check whether the formative tasks actually measure the same skills and whether instruction included enough guided practice. MAP RIT is not sensitive to a three-week unit. Adjust by reteaching data selection or CER reasoning if exit tickets show that, rather than by adding more content coverage. A reasonable success criterion is improvement from pre- to post-CER on evidence selection and reasoning, with at least 70% of students meeting the rubric's proficient level.
