3M update for week of April 15-19, 2019

Academic focus for this week:

Math: explore fractions and quadrilaterals; persevere; explain our thinking; work on accuracy in our calculations and our math language

English Language Arts (ELA): comprehension – author’s purpose; phonics – prefixes; grammar – possessive pronouns; writing – compare two passages and respond to prompt

Science: continue unit on weather and climate, with emphasis on wind and severe weather events

Words of the Week: their and our


This year, we will engage in several units of study, including weather and climate, simple machines, paleontology, and ecosystems. We will end each unit with an engineering project; this helps students to apply the knowledge gained during our science units.


In third grade, our major focus in mathematics is multiplication, division, and fractions. We will also explore quadrilaterals and firm up our addition/subtraction skills with 3-digit numbers. We will engage in daily problem solving, perseverance, attention to accuracy, and explanation of our mathematical thinking.


Third graders will firm up sentence-writing skills and learn to write paragraphs. We will write narrative, informational, and persuasive pieces. We will write in all curricular areas, including math, science, social studies, and English language arts.

English Language Arts

Third graders move from learning to read to reading to learn. We will read fiction, nonfiction, and poetry. We will learn to make text connections, infer, identify main idea and supporting details, and use visualization to comprehend what we read. We will read across all curricular areas.

Social Studies

This year, we will have two units of study: in January, we will explore human rights; in May, we will explore Helena history.
