OBJECTIVE. What will your students be able to do by the end of class?
Aim: REVIEW
ASSESSMENT. How will you know concretely
that all of your students have mastered the
objective?
KEY POINTS. What three to five main ideas or
steps will you emphasize in your lesson?
Unit Test next class
Unit 4 BIG IDEAS
Lesson Cycle
OPENING. How will you focus, prepare and engage students for the lesson’s
objective?
Do Now; Answer questions 1-5.
INTRODUCTION OF NEW MATERIAL. How will you convey the knowledge
and/or skills of the lesson? What will your students be doing to process this
information?
REVIEW BIG IDEAS-1.Heredity is the passing of traits from parents to offspring, and
MATERIALS.
REVIEW SHEETS
the DNA inside your cells’ nuclei helps determine nearly everything your body is and does.
2. Mitosis is the process where 1 nucleus of a body cells divides to form 2 identical nuclei
used for repair and growth.
3. Meiosis is the process where 1 nucleus of a fertilized cell divides twice to form four sex
cells with half as many chromosomes so that when organisms sexually reproduce, the
offspring won’t have double the chromosomes.
4. Some plants and animals can reproduce asexually which produce genetically identical
organisms, while some plants and animals can reproduce sexually to make genetically
different organisms.
5. Organisms with helpful adaptations are more likely to survive and reproduce which
eventually may become a separate species over time.
GUIDED PRACTICE. In what ways will your learners attempt to explain or do what
you have outlined? How will you monitor and coach their performance?
We do review sheet together Think Pair Share Style
INDEPENDENT PRACTICE. In what ways will your different learners attempt the
objective on their own? How will you gauge mastery?
Students work in groups to finish Unit 4 Review Sheet using notes…
CLOSING. How will you have students summarize what they’ve learned? How will
reinforce the objective’s importance and its link to past and future learning?
Students get extra credit for raising hand and answer questions. Finish Review Sheet
for extra credit.
DIFFERENTIATION: How will you differentiate your instruction to reach the diversity of learners in your
classroom?
Aim: How can review for the Unit 4 Test?
Do Now: Answer questions 1- 5.
